Question

i have a program assignment. this is the problem: Input a number and store the integers of the number to the elements of the array. print the integers and the sum of the integers from the array.

my program is wrong :( can someone help me please

Answer 1

what programming language are you using?

so at the moment what are you doing? using an array to store the numbers as the user enters them? then summing and outputting them after the user is done?

Answer 2

C++

Answer 3

this is my prog:


#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int x[0],sum=0,a,num,n;

cout<<"How many number do you wish to add: ";
cin>>a;
cout<<"Enter the numbers: ";
cin>>x[a];
for(int b=0;b<;b++)
{
cin>>x[b];
sum+=x[b];

cout<<"The sum of your numbers: "<<sum<<endl;
}
system("PAUSE");
return EXIT_SUCCESS;
}

Answer 4

do you have any limitations on what you're allowed to do?
for example are you allowed to use a list? or much you use an array?

Answer 5

no

Answer 6

i see so you are just having issues with creating the array

int* array;
int size;

cout << "How many numbers would you like to enter?" << endl;
cin >> size;

and then when you want to create it
array = new int[size];

and when you're done make sure you give back the memory

delete [] array;

Answer 7

wait ill try that

Answer 8

done. here is my new program but how can i repeat the question "ENTER THE NUMBER" depending on the number u want to input?

Answer 9

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int array[0],sum=0;
int size;

cout << "How many numbers would you like to enter?";
cin >> size;
cout<<"Enter your numbers ";

for(int x=0;x<size;x++)
{
cin>>array[x];
sum+=array[x];
}
cout<<"The sum is "<<sum;
system("PAUSE");
return EXIT_SUCCESS;
}

Answer 10

do you mean ask them to enter a number each time? you could output the statement in the for loop

Answer 11

done thank you !

Answer 12

here is my another problem and LAST poblem: Write a program that will search for the largest and smallest value in array of integers of length 10.

Answer 13

here is my program: #include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
float x[10],largest,smallest;

cout<<"Enter a number ";
cin>>x[0];
largest=x[0];

for(int a=0;a<10;a++)
{
cin>>x[a];
if(x[a]>largest)
largest=x[a];

cout<<"The largest number is "<<largest;
}
else {
(x[a]<largest)
smallest=x[a];
cout<<"The smallest number is "<<smallest;
}
system("PAUSE");
return EXIT_SUCCESS;
}

Answer 14

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
int* array;
int sum=0;
int size;

cout << "How many numbers would you like to enter?";
cin >> size;
cout<<"Enter your numbers ";
array = new int[size]; // init the array to
for(int x=0;x<size;x++)
{
cin>>array[x];
sum+=array[x];
}
cout<<"The sum is "<<sum;
system("PAUSE");
delete [] array; // clean up the memory

return EXIT_SUCCESS;
}

Answer 15

oooops sorry ! thats wrong.

Answer 16

here is the real program that i made:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
float x[10],largest,smallest;

cout<<"Enter a number ";
cin>>x[0];
largest=x[0];

for(int a=0;a<10;a++)
{
cin>>x[a];
if(x[a]>largest)
largest=x[a];

cout<<"The largest number is "<<largest;
}
else {
(x[a]<largest)
smallest=x[a];
cout<<"The smallest number is "<<smallest;
}
system("PAUSE");
return EXIT_SUCCESS;
}

Answer 17

ok i've looked at the code, where are you having problems ?

Answer 18

it doesnt run :(

Answer 19

you're missing some curly brackets { after the if(x[a]>largest)

and } after cout<<"The smallest number is "<<smallest;

and what's with (x[a]<largest) ?

Answer 20

actually im doing trial and error. :) but i cant print the largest and smallest number that entered

Answer 21

im done ! lol :D i did it

Answer 22

good work =)

Answer 23

but how can i repeat again "ENTER THE NUMBER" ??

Answer 24

here is my final program:


#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
float x[10],largest,smallest;
cout<<"Enter a number ";
cin>>x[0];
largest=x[0];
for(int a=1;a<10;a++)
{
cin>>x[a];
if(x[a]>largest)
largest=x[a];

if(x[a]<smallest)
smallest=x[a];

}
cout<<"The largest number is "<<largest<<endl;
cout<<"The smallest number is "<<smallest<<endl;

system("PAUSE");
return EXIT_SUCCESS;
}


how can i repeat the "ENTER THE NUMBER" ??

Answer 25

put

cout<<"Enter a number ";

into the for loop

Answer 26

just it? or together with the cin>>x[0];
largest=x[0];??

Answer 27

i didnt work. well actually it run but it double the number

Answer 28

like

for(int a=1;a<10;a++)
{
cout<<"Enter a number ";
cin>>x[a];

if(x[a]>largest)
largest=x[a];

if(x[a]<smallest)
smallest=x[a];
}

Answer 29

the largest number didn't work.

Answer 30

that's strange from the code i can see it should have, one sec i'll compile it and have a look

Answer 31

the code you sent before is working fine =\

Answer 32

done :D

Answer 33

i did this:

for(int a=0;a<10;a++)
{
cout<<"Enter a number ";

largest=x[0];
cin>>x[a];
if(x[a]>largest)
largest=x[a];

if(x[a]<smallest)
smallest=x[a];

}

Answer 34

do have any facebook account? i will add u so that when i have another problem. i can ask u about it.

Answer 35

just ask on here that way if i'm not around anyone can help =)

Answer 36

ok sure. wait i saw this problem here on my book. it says " Write a program that will print the seven positioned elements in an array of 10 floating numbers."

Answer 37

that confused me. what would be the program look like ?

Answer 38

ndani14 helps everybody...how kind he is,don't you think so?he helped me a lot:))

Answer 39

yup i think he is really kind and helpful. God Bless him. Thank you again ndani14!

Answer 40

so you have an array of 10 floats and it wants to know how you would access the seventh element?

eg.

float myFloats[10];

myFloats[x]; // what should x be?

Answer 41

what does the "even positioned element" mean? the elements like: 2,4,6,8,10 elements?

Answer 42

the numbers that u input to the 2,4,6,8,10th element will print out ?? is that it ?

Answer 43

almost except arrays begin their indexing at 0 so the 1st element is 0, 2nd is 1 and so on
