Thread: Im getting one error and six warnings i think im overlooking something

Code:

#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>
#define LINE_MAXLENGTH 80




int main()

    float a, b;
    char operations;




    FILE* cmd = fopen("CommandsProj2.dat", "r");








    if (cmd == NULL)
    {
        printf("Error Code (404)");
        return EXIT_FAILURE;
    }




    int line[LINE_MAXLENGTH + 1];
    while (fgets(line, LINE_MAXLENGTH + 1, cmd))
    {
        float result;
        line[strcspn(line, "\n")] = '\0';
        if else(strcmp(line, "DA") == 0)

Just tell me what's wrong with it if I need to start the whole program over then tell me telling me all this is wasting everyone's time

In any case, your problem stems from the fact that you're declaring line as an array of int, rather than an array of char. fgets() and strcspn() both require a char* as their first argument, so an array of int (which decays to int*) will not work.

Edit:
After looking further, I can see that there are so many problems with your code that make it very clear that you don't understand what you're doing at all. It appears that you need to buy a C book, and start at the very beginning. It's clear that this program is well above your ability level at this time.

Lol yes it very much is don't worry after this is done I wouldn't need this anymore I'm clearly not gonna be a programmer not my cup of tea at all. But I know how to open and read a file and print it and also print the answers in a loop but adding the round, separate, partition, and upper lower case is even more beyond me.
