C Program Print a comma-separated list of numbers from 1 to 10

The if statement within the body of the for loop is used to print a comma after each value of the loop variable except the last one.

Consider the code given below to print a comma-separated list of numbers from 1 to 10:

#include<stdio.h>
void main() {
 int i;
 clrscr();
 printf("Print a comma-separated list of numbers from 1 to 10 :\n");
 for (i = 1; i <= 10; i++) {
   printf("%d", i);
   if (i < 10)
     printf(", ");
 }
 printf("\n");
 getch();
}
