//This is how i call it inside the main
writeResultsToFile(FILE *f,arrTypeLabels[3][7],sortNames[4][11],times[4][3],n);

the code inside it is right i tested it without the funtion, it works , i just dont know how to call it as a funtion if anybody can help.

Expected expression before FILE, and conflicted type errors..............................................

CodePudding user response：

FILE *f;
writeResultsToFile(f,arrTypeLabels,sortNames,times,n);

i am just writting this
