So I am trying to take a string and replace a certain character with another in the string. The function doesn't
return anything, but rather changes the string itself. Why would I be getting a bus error 10?

void replaceChar(char *src, char oldChar, char newChar){
    //get length of source string.
    int length = 0;
    length = (int) strlen(src);
    
    char *newSrc = (char *)malloc((length + 1) * sizeof(char));
    
    //checks and manipulates the string.
    int i;
    char c;
    for (i = 0; i < length; i++){
        if (src[i] == oldChar){
            src[i] = newChar;
        }
    }
}

I feel like maybe I can't overwrite existing characters in a string, but I don't know how else to implement this without returning anything, which I am not allowed to do.

Why do you allocate new memory if you just override the old one? You also never use the variable c.

Anyway, I suspect that your problem isn't with the code you've shown us, but with how you call it. Are you calling it with a string literal as the argument by any chance? String literals may not be modified and are often stored in read-only memory.
