How to convert text to binary code in C

Answer 1

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

void text2bin(const char *txt, char *bin) {
    int len = strlen(txt);
    bin[0] = '\0'; // Initialize the bin string
    
    char temp[1024] = "";
    strcpy(temp, txt);

    for (int i = 0; i < len; i++) {
        char binary[9] = {0}; // 8 bits for binary representation + null terminator
        for (int j = 7; j >= 0; j--) {
            binary[j] = (temp[i] & 1) ? '1' : '0';
            temp[i] >>= 1;
        }
        strcat(strcat(bin, binary), " ");
    }
}

int main() {
    const char *txt = "C Programming";
    char bin[256] = {0}; 

    text2bin(txt, bin);
    
    printf("%s\n", bin);

    return 0;
}
