Write a program that works as a simple calculator.
1.It reads a character (ch)
2.If ch is among ‘+’, ‘-’, ‘*’, ‘/’ or ‘%’ it furthur takes two numbers (N1 and N2 as input). It then performs appropriate appropriate operation between numbers and print the number.
3.If ch is ‘X’ or ‘x’, the program terminates.
4.If ch is any other character, the program should print ‘Invalid operation. Try again.’ and seek inputs again (starting from character).–here is my code—
the ide link u send only shows hello world code send it again
In case it does not work
#include<iostream>
using namespace std;
int main() {
long long int n1,n2,a,b,c,d,e;
char ch;
// cin>>ch; //input it inside
// cin>>n1; dont input here as we dont know if char is valid or not
// cin>>n2;
do {
cin>>ch;
if(ch=='+'){
cin>>n1;//input insode
cin>>n2;
a=n1+n2;
cout<<a<<endl;
}
else if(ch=='-'){
cin>>n1;//input insode
cin>>n2;
b=n1-n2;
cout<<b<<endl;
}
else if(ch=='*'){
cin>>n1;//input insode
cin>>n2;
c=n1*n2;
cout<<c<<endl;
}
else if(ch=='/'){
cin>>n1;//input insode
cin>>n2;
d=n1/n2;
cout<<d<<endl;
}
else if(ch=='%'){
cin>>n1;//input insode
cin>>n2;
e=n1%n2;
cout<<e<<endl;
}
else {
if(ch != 'x' && ch != 'X') {
cout<<"Invalid operation. Try again."<<endl;
}
}
}while( ch != 'x' && ch != 'X');
// {remove this brackets not a while loop
// }
return 0;
}
