Use the keyword if to check if something is true.
Here are some simple examples:
int center = 0; if(x == 0) center = 1;
int center; if(x == 0) center = 1; else center = 0;
FILE *fp = fopen("myfile", "r+t"); if(fp) { // your code here } fclose(fp);
Note that if(fp) is the same as if(fp != 0).
Note: Don't forget to have the equal signs twice.
