Thread: Find and Replace Text Function

im working on a find and replace text function now, with not alot of luck

heres what i have so far

Code:

int replace(char *source, char search[], char replace[]) {
    char *value = (char *)malloc( ( strlen(source) - strlen(search) ) + strlen(replace) );

    char *start = strstr(source, search);
    strncpy(value, source, *start); 
    
    printf("%s\n", value);
    
    return 0;
}

int main() {
    char temp[] = "testing a new idea";
    replace(temp, "new", "WORKING");


    return 0;
}

i want to look for string search in string source and copy it to a seperate string. then i want to strcat the replace and copy what was left over from string.

right now the strncpy(value, source, *start); line doesnt seem to be working. i now its a memory adress im giving it, but is there and way i can use it like a subscript?

i was think about making a function to figure out the subscript from the address and the string name, but it really cant be done. characters can repeat them self.
