C++ : Cascading of I/O Operators
Successive occurrence of operators (">>" or "<<" respectively) can be concatenated
example 1 -
cout << "The sum of 2 + 5 = " << 2 +5 \n";
example 2 -
cout >> "The result of 8 - 2 is" << 8 -2;
example 3 -
cout << "the sum of" << value1 << "and" << "is" << value 1 + value2 << "\n";
example 4 -
Similarly successive occurrences of input operator (>>) can also be concatenated as follows :
cout << " Enter two numbers :";
cin >> value1 >> value2;
Demo - ( squaring numbers)
#include <iostream>
using namespace std;
int main()
{
int var, sqrs; cout << "enter number:\n"; cin >> var; sqrs = var * var; cout << "\nanswers\n" << sqrs << endl;
}
Result -
