You can use this: int max(int x, int y, int z){ if(x>y){ if(x>z) return x; else return z; } else{ if(y>z) return y; else return z; } }

#include <iostream> using namespace std; int max_of_three(int a, int b, int c) { int max_so_far = 0; if (a > b) { max_so_far = a; } else { max_so_far = b; } if (c > max_so_far) { return c; } return max_so_far; } int main() { cout << max_of_three(1, 2, 3) << endl; cout << max_of_three(1, 3, 2) << endl; cout << max_of_three(2, 1, 3) << endl; cout << max_of_three(2, 3, 1) << endl; cout << max_of_three(3, 1, 2) << endl; cout << max_of_three(3, 2, 1) << endl; } Result: 3 3 3 3 3 3

Here is the answer with no IFs and Termary Operators. template<typename T> T max(T const&a,T const&b,T const&c) { return a*(a>=b&&a>=c)+b*(a<b&&b>=c)+c*(a<c&&b<c); }

First version can only find max between 3 numbers, other takes an array which can be any size. int max1(int a, int b, int c) { int arr[3] = {a, b, c}; int maxNum = arr[0]; for (int i = 1; i < 3; i++) { if (arr[i] > maxNum) maxNum = arr[i]; } return maxNum; } int max2(int arr[]) { int size = sizeof(arr) / sizeof(arr[0]); int maxNum = arr[0]; for (int i = 1; i < size; i++) { if (arr[i] > maxNum) maxNum = arr[i]; } return maxNum; }

you wrote parentheses with else() are these necessary?

No, actually I did a mistake there, else doesn't have parentheses it would be else{ /*your code*/ } I've fixed this...

can we write like that in defining a function for max number if (x>b && x>c) { return x;} else if (b>a && b>c) { return b;} else return z;
