Q1 - Write a program to check whether two numbers (entered by user) are equal or not
#include<iostream>
using namespace std;
int main(){
    int a;
    cout<<"Enter A Value: ";
    cin>>a;
    int b;
    cout<<"Enter B Value: ";
    cin>>b;
    
    if(a==b){
        cout<<"A and B are equal";
    }else{
        cout<<"A and B are not equal";
    }
 
    //if you want to get output as a boolean value then you print bool return 0 for flase or 1 is true
    // if(a==b){
    //     cout<<true;
    // }else{
    //     cout<<false;
    // }
    
    return 0;
}

Q2 - Write a program to take the values of two variables a and b from the keyboard and then check if
both the conditions 'a < 50' and 'a < b' are true.


#include<iostream>
using namespace std;
int main(){
    int a;
    cout<<"Enter A value: ";
    cin>>a;
    int b;
    cout<<"Enter B value: ";
    cin>>b;
    
    if(a<50 && a<b){
        cout<<true;
    }else{
        cout<<false;
    }
    return 0;
}
   


Q3 - There are 45 total pupils in the class, 25 of whom are boys. Write a program to find how many
girls received grades "A" if 17 boys made up 80% of the students that received grades "A".
#include<iostream>
using namespace std;
int main(){
    int total, boys, girls;
    cout<<"Enter the total number of student: ";
    cin>>total;
    total= (80*(total))/100;
    boys = 17;
    girls = total - boys;
    
    cout<<"Total girls recieved A grade: "<<girls<<endl;
    return 0;
}

Q4 - Write a program to calculate the sum of the first and the second last digit of a 5 digit number.

#include<iostream>
using namespace std;
int main(){
    int a;
    cout<<"Enter the 5 digit number: ";
    cin>>a;
   int sum;
    int first = a/10000; //first digit
    a = a%10000;
    int second = a/1000; //second digit
    a = a%1000;
    int third = a/100; //third digit
    a = a%100;
    int fourth = a/10; //fourth digit
    int fifth = a%10; 
   sum= first+fourth;
   cout<<"First and second last digit of sum is: "<<sum<<endl;
   return 0;
}



Q5 - Write a program to calculate the sum of digits of a 3 digit number.


#include<iostream>
using namespace std;
int main(){
    int num, first, second , third, sum;
    cout<<"Enter the 3 digit number: ";
    cin>>num;
    
    first = num/100;
    num %= 100;
    second = num/10;
    num %= 10;
    third = num/1;
    num %= 1;
    
    sum = first + second + third;

    cout<<"Total three digit sum: "<<sum<<endl;
    
    return 0;
}



Q6 - Design a calculator to perform basic arithmetic operations (+,-,/,*,%)
#include<iostream>
using namespace std;
int main(){
    char operators;
    cout<<"Enter the following operators (+ - * / %): ";
    cin>>operators;
    float a, b;
    int c, d;
    
    if(operators=='%'){
         
                    cout<<"Enter c value: ";
                    cin>>c;
                    cout<<"Enter d value: ";
                    cin>>d;
    }else{
          
          cout << "Enter the a value: ";
          cin >> a;
          cout<< "Enter the b value: ";
          cin>>b;
    }
    
    
    
    switch(operators){
        case '+':
                    cout << a << " + " << b << " = " << a + b;
                     break;
        case '-':
                    cout << a << " - " << b << " = " << a - b;
                     break;
        case '*':
                    cout << a << " * " << b << " = " << a * b;
                     break;
        case '/':
                    cout << a << " / " << b << " = " << a / b;
                     break;
                    
         case '%':  
                   
                    cout << c << " % " << d << " = " << c % d;
                     break;
                  
        default: 
                    cout<<"Enter the value by given instruction! ";
                    break;
    }
    return 0;
