Find the Largest Number Using the In-built max() Function
C++ provides a library function named max() to find the maximum out of two numbers. It is defined inside the <algorithm> header file. We can use this function to find the maximum out of three numbers as shown in the below program.
C++ Program to Find the Maximum Among the Three Numbers using max() Function
C++
// C++ Program to find the// greatest of three numbers// using In-built max()#include <algorithm>#include <iostream>using namespace std;// Driver codeint main(){ int a, b, c; a = 10, b = 20, c = 30; int ans; ans = max(a, max(b, c)); cout << ans << " is the largest"; return 0;} |
Output
30 is the largest
