Question

i have to write programme to find second largest number.just give me a hint.
1 MEDAL FOR SATISFACTORY HINT.

Answer 1

Which programming language?

Answer 2

@Harsha19111999
in c
just hint only

Answer 3

Oh. If it is of two numbers, you can use the "if" function

Answer 4

@Harsha19111999
it is not two nos.it is '''n' number which is not known in advance.use willl choose how many no.will he enter.

Answer 5

Then, this program will help you
#include <stdio.h>
int main(){
int i,n;
float arr[100];
printf("Enter total number of elements(1 to 100): ");
scanf("%d",&n);
printf("\n");
for(i=0;i<n;++i) /* Stores number entered by user. */
{
printf("Enter Number %d: ",i+1);
scanf("%f",&arr[i]);
}
for(i=1;i<n;++i) /* Loop to store largest number to arr[0] */
{
if(arr[0]<arr[i]) /* Change < to > if you want to find smallest element*/
arr[0]=arr[i];
}
printf("Largest element = %.2f",arr[0]);
return 0;
}

Answer 6

@Harsha19111999
without using array.

Answer 7

How can you do it without an array? Where will you assign the values? Explain your question

Answer 8

Ok so without an array you need two variables. One to store the first number user inputs and another to store the highest overall. You would use a loop to get input and to check the two numbers at the same time, saving the highest...

Answer 9

Since you need the second highest overal, you need at least 3 variables:
highest, second_highest, user_input.

I think the best way would be to loop until you input an exit value. That will depend on the allowed range of numbers. A common exit number for a loop is -999.

pseudo pseudo code:
while user_input <> -999 do
{
input user_input;
if user_input > highest then second_highest = highest and highest = user_input;
if user_input > second_highest and user_input < highest then second_highest = user_input;
}

Answer 10

g#include<stdio.h>
main()
{
int n,m,i,max;

printf("How many numbers(n) you going to enter:");
scanf("%d",&n);
printf("Enter the numbers:");
scanf("%d",&m);
max=m;
for(i=2;i<=n;i++)
{
scanf("%d",&m);
if(m>max)
max=m;
}
printf("The Largest Number is %d",max);
}

Output:

How many numbers(n) you going to enter:5
Enter the numbers:
25
410
362
5
56
The Largest Number is 410

With Using Arrays

Program:

#include<stdio.h>
#include<conio.h>
void main()
{
int max_num(int a[],int n);
int max,i,n;
int a[50];
clrscr();
printf("Enter n number:");
scanf("%d",&n);
printf("Enter the numbers:");
for(i=0;i<n;i++)
scanf("%d",&a[i]);
max=max_num(a,n);
printf("The largest number is %d",max);
getch();
}
int max_num(int a[],int n)
{
int i,m=0;
for(i=0;i<n;i++)
{
if(a[i]>m)
m=a[i];
}
return m;
}

output:
Enter n number:10
Enter the numbers:
123
456
789
963
852
147
5
56
600
753
The largest number is 963

Answer 11

this has one with arrays and one with out arrays

Answer 12

@danielgomez755
i wanted second largest,not largest.

Answer 13

Three variables: testNumber, secondLargest, largest

if( testNumber > secondLargest )
{
/* switch them */
if( secondLargest > largest )
/* switch them */
}
printf( "%d", secondLargest );
