C++
// C, C++ program to demonstrate// functionality of strncmp()#include <cstring>#include <iostream>using namespace std;int main(){ // Take any two strings char str1[10] = "akash"; char str2[10] = "aksh"; // Compare strings using strncmp() int result = strncmp(str1, str2, 4); if (result == 0) { // num is the 3rd parameter of strncmp() function cout << "str1 is equal to str2 up to num characters" << endl; } else if (result > 0) cout << "str1 is greater than str2" << endl; else cout << "str2 is greater than str1" << endl; cout << "Value returned by strncmp() is: " << result << endl; return 0;} |
