Write a C++ program to represent call by value.

#include<iostream> using namespace std; void change(int data); int main() {   int data=3;   change(data);   cout<<“value “<<data<<endl;   return 0; } void change(int data) {    data =5; } OUTPUT

Write a C++ program to represent the function overriding using AVERAGE() function.

#include <iostream> #include <string> using namespace std; int avrg( int , int ); int avrg( int , int, int); float avrg( float, int); int avrg(char, char); int main() {   int average;   cin >> average;   int averageI;   cin >> averageI;    float x;    cin >>x; float y;   cin >>y;   float averageF = avrg(x,y);   char averageC = avrg('x','y');...

Write a program in C++ to read and write the values in different variables using cascading of >> and <<

#include <bits/stdc++.h> using namespace std; int main(void) { int a; float b; char c; char str[50] ; cin>>a>>b>>c>>str; cout <<“integer – “<<a<<“\n”<<“float – “<<b<<“\n”<<“character- “<<c<<“\n”<<“string- “<<str; return 0; } OUTPUT

Write a C++ program to read and write the values in different types of variables using cin and cout.

#include <iostream> using namespace std; int main() {      int i;      cout<< "Enter an integer value: ";      cin >>i;      cout<< "Number entered is"<<i;      cout<< " double of the number is"<<i*2<<"\n";      return 0; } OUTPUT
