Convert C++ byte array to a C string

Question

I\'m trying to convert a byte array to a string in C but I can\'t quite figure it out.

I have an example of what works for me in C++ but I need to convert it to C.

Answer 1

Strings in C are byte arrays which are zero-terminated. So all you need to do is copy the array into a new buffer with sufficient space for a trailing zero byte:

#include 
#include 

typedef unsigned char BYTE;

int main() {
    BYTE byteArray[5] = { 0x48, 0x65, 0x6C, 0x6C, 0x6F };
    char str[(sizeof byteArray) + 1];
    memcpy(str, byteArray, sizeof byteArray);
    str[sizeof byteArray] = 0; // Null termination.
    printf("%s\n", str);
}
