Hi man,
Here is the thing.
Code:#include <stdio.h> #include<stdlib.h> int main() { int iNum; char str[10]; printf("Please enter a positive integer, or press 0 to quit\n\n"); scanf("%d",&iNum); while ( iNum != 0) { itoa(iNum,str,10); //call my function here//pass str as parameter.get return value in a pointer or char array. printf("Enter another integer or 0 to quit\n\n"); scanf("%d",&iNum); } }
