The for loop is usually used when the number of iterations is predetermined.
The format of the for loop is
for (expr1;expr2;expr3){
s1;
s2 ;
}
- expr1 is executed only once before looping.
- expr2 is a Boolean expression. If not given, it is assumed to be true.
- If expr2 is false, the loop is terminated.
- After execution of the repeat section, expr3 is executed
- The expressions expr1, expr2 and expr3 are all optional.
#include <stdio.h>
main(){
int i,n = 5;
for(i = 0; i < n; i = i+1){
printf("the numbers are %d \n",i);
}
}
the numbers are 0
the numbers are 1
the numbers are 2
the numbers are 3
the numbers are 4
