    error: expected identifier or ( before while

    I have used this bit of code before without problems, however, when using it now, i'm getting the error listed in the title...

    I don't see anything wrong with it.. any help?

    Code:
            //Prompting user for Input file//
            while(resp == 'Y' || resp == 'y'){
                    printf("Please enter the file you'd like to read from: ");
                    scanf("%s", fileInName);
                    if((fopen(fileInName, "r")) == NULL){
                            printf("Could not open requested file. Would you like to enter another file? [Y/N]: ");
                            scanf("%*c %c", &resp);
                    }
                    else {
                            inFile = fopen(fileInName, "r");
                            break;
                    }
                    if(resp == 'n' || resp == 'N')
                            exit(1);
    
            }

    so what do you have before while?
    and why are you calling fopen twice to open same file?
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    That code looks fine to me. What comes before it? Perhaps a missing ; or unmatched parens or curly braces.

    I don't immediately see any problem, but I'm willing to bet the error is actually somewhere above this snippet of code.

    Since the error message says something about "before while", I'm guessing we need to see a bit more code leading up to this point.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    This is everything that exists above that bit of code

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #define MaxSize 30
    int main(){
    
            FILE *inFile;
            FILE *outFile;
    
            char resp = 'Y';
            char fileInName[20];
            char fileOutName[20];
    
            int k;
            int numRecords;
    
            //Define struct//
            struct employee {
                    char surname[10];
                    char given[10];
                    char dept[20];
                    float payRate;
                    char eyeColor[8];
            }

    Yeah, your struct needs a trailing ;

    Code:
    struct employee {
                    char surname[10];
                    char given[10];
                    char dept[20];
                    float payRate;
                    char eyeColor[8];
            }  ;
    and defining struct in main means the definition of this struct is local to main function only.
    Most of the time, I can assure you don't want it.
