Question

Write a program that accepts a 7-9
digit integer and echoes the number with commas
between every three digits from the right. Test it with the
numbers 1234567, 987654321, 20300045, & 10000000.
this is the program i have so far
#include using namespace std; int main () { int first3, middle3, last3; int original, temp; cout<<"enter a 7-9 digit number"<>original; temp=original/1000; last3=original%1000; first3=temp/100; middle3=temp%1000; cout<<"the number with a comma is "< 13 years ago

Answer 1

get a string, loop over from 1 - strlen(string)-1 and print each character with a comma..

Answer 2

Since you're outputting it with commas, it has to be a string, it can no longer be an int. Think about the problem working it as a string.

Answer 3

since it's seven to nine characters you can use integers too.You just have to extract their digits

Answer 4

well this what my teacher showed me then he said that i have to add four more lines to the middle3 and last3; i had it once but i forget it

Answer 5

please can someone help me with this it is already late

Answer 6

#include <cstdio>
#include <stack>
using namespace std;
stack<int> S;
void print(long long a)
{
while(a>0) {
S.push(a%10);
a/=10;
}
printf("%d",S.top());
while(!S.empty()) {
printf(",%d",S.top();
s.pop();
}
}
int main(void)
{
long long a;
scanf("%lld",&a);
print(a);
return 0;
}

I didn't test it, i hope it works

Answer 7

i am not supposed to use a while loop

Answer 8

why?

Answer 9

ah, every three digits :P i thought it would be every digit.. my code needs a small correction then.

Answer 10

because while we were learning this program my teacher didnt teach us any of the looping statements

Answer 11
