Relational comparison result unused error. code will not run

Code I used is same as in the video, but I am getting the error "Relational comparison result unused" on the line with "for(int i=0; i<3, i++) {

Please help me troubleshoot. I cannot seem to figure it out.

Thanks!

include <stdio.h>

int main() {

int many [] = {2,4,8};
int sum = 0;
for (int i=0; i < 3, i++) {
    sum+=many[i];
    printf("sum %d\n",sum);
}
return 0;

}

Hi, you used comma instead of semicolon in the condition, after i < 3 try using semicolon:

int main() {
  int many [] = {2,4,8};
  int sum = 0;
  for (int i=0; i < 3; i++) {
    sum+=many[i];
    printf("sum %d\n",sum);
  }
  return 0;
}
