C/C++ difference's between strncmp() and strcmp.

strncmp() and strcmp compares two strings using ASCII character comparison. strncmp takes one additional parameter as number to characters upto which a string is to be compared. It is very useful as if a string is not valid, then strcmp will not be able to complete its operation. strcmp searches for end character ('/0') at string end to finish its operation. strncmp uses no. of characters to end its operation and thus is safe.

Example

#include <stdio.h> int main() {    char str1[] = "TutorialsPoint";    char str2[] = "Tutorials";    // Compare strings with strncmp()    int result1 = strncmp(str1, str2, 9);    if(result1 == 0){       printf("str1 == str2 upto 9 characters!\n");    }    // Compare strings using strcmp()    int result2 = strcmp(str1, str2);    if(result2 == 0){       printf("str1 == str2!\n");    } else {       if(result2 > 0){          printf("str1 > str2!\n");       } else {          printf("str1 < str2!\n");       }    }    return 0; }

Output

str1 == str2 upto 9 characters! str1 > str2!
