Return Statement in C++ Programming Language
Return Statement in C++
A return statement ends the processing of the current function and returns control to the caller of the function. A value-returning function should include a return statement, containing an expression.
If an expression is not given on a return statement in a function declared with a non-void return type, the compiler issues an error message.
If the data type of the expression is different from the function return type, conversion of the return value takes place as if the value of the expression were assigned to an object with the same function return type.
Syntax for Return Statement in C++
return[expression];
return; /* Returns no value */
return result; /* Returns the value of result */
return 1; /* Returns the value 1 */
return (x * x); /* Returns the value of x * x */
/* illustrate Methods returning a value using return statement in C++ code example */
#include <iostream>
using namespace std;
// non-void return type
// function to calculate sum
int SUM(int a, int b)
{
int s1 = a + b;
// method using the return
// statement to return a value
return s1;
}
// Driver method
int main()
{
int num1 = 10;
int num2 = 10;
int sum_of = SUM(num1, num2);
cout << "The sum is " << sum_of;
return 0;
}
This is a C++ Program code to check 'sparsity' of a matrix. If the number of zeros in a matrix exceeds (n*m)/2, n and m is the dimension of the matrix, matrix is sparse matrix. Enter the
A 'positive integer' which is only divisible by 1 and itself is known as prime number. So 13 is a prime number because it is only divisible by 1 and 13 but, 15 is not prime number because
This C++ program takes a sentence from user and "Reverses" that sentence using recursion. This sample doesn't 'use string' to reverse the sentence or store the sentence. User is asked
