Anyone to help me understand this c language code.

Question

This loop variable (m) is so confusing.

*sum of array*/

#include <stdio.h>

int main(){
int m;
int n[5];
int sum;

for(m=0;m<=4;m++){
printf("Enter a value:\n");
scanf("%d",&n[m]);
}

for(m=0;m<=4;m++){
sum=sum+n[m];
}

printf("\nThe sum of the elements is:%d",sum);

return 0;
}

Answer 1

m is defined outside of the loops, it then is equaled to 0 and is then looped 5 times. Then it is reset in the next for loop (to 0 again) and is looped 5 times.

Answer 2

If you are also confused about how m is used within these for loops:

M is being incremented each loop and in this case is looking through the array 'n'
