Your file contains 0x1A , which means EOF and reading it will stop reading when the file is opened in text mode.

Try opening your file in binary mode.

Here is a test code:

#include <stdio.h>

int main(void) {
    const char *fileName = "codeText.txt";
    FILE* fp;
    int input;

    fp = fopen(fileName, "r");
    if (fp==NULL) return 1;
    puts("text mode:");
    while((input = getc(fp)) != EOF) printf("%02X\n", (unsigned int)input);
    fclose(fp);

    fp = fopen(fileName, "rb");
    if (fp == NULL) return 1;
    puts("binary mode:");
    while((input = getc(fp)) != EOF) printf("%02X\n", (unsigned int)input);
    fclose(fp);

    return 0;
}
