Thread: Converting binary data in a txt file into HEX

]Hi I'm not the best at C but I'm trying to write a C function that basically opens a text file with assembler language does a syntax error check on it and then converts the binary data into hex.

This is my code so far:

Code:

#include <stdio.h>
#include <string.h>


int main(void) 
{
    FILE*fname;
    char prompt;
    char filename[15];
    char text[100];


    printf( "Please enter the name of the file you wish to open: \n" );


    fgets(filename, sizeof(filename), stdin);
    filename[strlen(filename)-1]='\0';


    fname = fopen(filename, "r+");
    if (fname == NULL)
    {
        printf( "ERROR the file you have chosen cannot be opened \n" );
        printf( "Please make sure the file exists \n");
        return;
    }
    while (fgets(text,100,fname) != NULL)
        printf("\n%s", text);
    scanf("\n%c",&prompt);
}
