Answer:
The program is written in C++ language and given below in explanation section. All bold faced words are C++ keywords and symbols. Nested if-else decision branch is used to determine smallest number of all three integers. First of all you have input three integers then the program prints smallest integer of all
Explanation:
#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;
}
