C++ Program to Find Largest Number Among Three Numbers
The largest number among three numbers can be found using if statement multiple times. This is given in a program as follows −
Example
#include <iostream>
using namespace std;
int main() {
int a = 5 ,b = 1 ,c = 9;
if(a>b) {
if(a>c)
cout<<a<<" is largest number";
else
cout<<c<<" is largest number";
}else {
if(b>c)
cout<<b<<" is largest number";
else
cout<<c<<" is largest number";
}
return 0;
}Output
9 is largest number
In the above program, firstly, a is compared to b. If a is greater than b, then it is compared to c. If it is greater than c as well, that means a is the largest number and if not, then c is the largest number.
if(a>b) {
if(a>c)
cout<<a<<" is largest number";
else
cout<<c<<" is largest number";
}If a is not greater than b, that means b is greater than a. Then b is compared to c. If it is greater than c, that means b is the largest number and if not, then c is the largest number.
else {
if(b>c)
cout<<b<<" is largest number";
else
cout<<c<<" is largest number";
}
