Answer to Question #123090 in C for warda

Question

Write a program in C programming language, that will open a bitmap image file in read mode, reads its contents, and display it on the screen

Answer 1

You need first open bmp file in a binary mode:

FILE* f = fopen("1.bmp", "rb");

Then read file byte by byte and display its hex values:

while (!feof(f))

printf("%02X ", fgetc(f));

Close file after using:

fclose(f);

Whole source:

#include <stdio.h>

int main()

{

FILE* f = fopen("1.bmp", "rb");

if (f == 0)

return 1;

while (!feof(f))

printf("%02X ", fgetc(f));

fclose(f);

return 0;

}
