Let's see the simple program of for loop that prints table of 1.

  1. #include<stdio.h>  
  2. int main(){  
  3. int i=0;        
  4. for(i=1;i<=10;i++){      
  5. printf("%d \n",i);      
  6. }     
  7. return 0;  
  8. }     

Output

1
2
3
4
5
6
7
8

  5. scanf("%d",&number);    
  6. for(i=1;i<=10;i++){      
  7. printf("%d \n",(number*i));
