"Nested-if-else" statements c++
When an "if-else" structure is placed in another "if-else" structure, it is called "nested-if-else" structure. It is used for multiple selection.
Its general syntax is:
if (condition-1)
statement-1;
else if (condition-2)
statement-2;
else if (condition-3)
statement-3;
--------------------------------
--------------------------------
else if (condition-m)
statement-m
else
statement-n;
Example:
Write a program to perform simple arithmetic operation by using "nested-if-else" structure.
#include <iostream.h>
main()
{
int a,b;
char op;
cout <<"Enter 1st integer, operator & 2nd integer\n";
cout << "Press Enter Key";
cin >>a>>op>>b;
if (op=='+')
cout << "Addition = " <<(a+b);
else if (op=='-')
cout << "Subtraction=" <<(a-b);
else if (op=='/')
cout << "Division=" << (a/b);
else if (op=='%')
cout << "Remainder=" << (a%b);
else
cout << "Invalid Input";
}
