The software is written in C++ and may be found in the explanation section below. C++ keywords and symbols are all capitalized. The least number of all three integers is determined via a nested if-else decision branch. After you've entered three integers, the application prints the least of them all.
<h3>
What is the example of C++?</h3>
#include <iostream>
using namespace std;
int main() {
   int num1,num2,num3;
   cout<<"enter first integers"<<endl;
  cin>>num1;
   cout<<"enter second integers"<<endl;
   cin>>num2;
  cout<<"enter the third integers"<<endl;
   cin>>num3;
   if(num1<num2){
      if(num1<num3){
           cout<<"Smallest integer is "<<num1<<endl;
     } else{
           cout<<"Smallest integer is "<<num3<<endl;
       }
  }else {
  if(num2<num3){
     cout<<"Smallest integer is "<<num2<<endl;
 } else{
     cout<<"Smallest integer is "<<num3<<endl;
      }
}
return 0;
}
