C++ programming tutorial 2

Control statement in C++ PROGRAMMING -

1. if-else statement :
   there are types below of if else statement so they are -

    1. if-statement 
    In this if statement a condition was entered if the condition was match or say what we write in condition on it was true then program was run if it was false then the program in if statement was not run .

Syntax -
if(Condition){
//code you want to run
}

PROGRAM -

// if-else statement 

#include<iostream>
using namespace std;

int main()
{
    int a ;
    cout<<"If the entered integer in equal to the condition they it run "<<endl;
    cin>> a;
    if(a<=6)
    {
        cout<<"Program was running";
    }

    return 0;
}

Output -
If the entered integer in equal to the condition they it run
3
Program was runningCondition was false
Program not run   

 2. if-else statement :
In this statement if-else condition is used at that situation when if condition was false the else statement run and if it is true then if-statement program run .

Syntax -

if(condition)
{
// code in the condition
}
else 
{
//code in the condition
}

Program -
// if-else statement

#include <iostream>
using namespace std;

int main()
{
    int a;
    cout << "If the entered integer in equal to the condition they it run " << endl;
    cin >> a;
    if (a <= 6)
    {
        cout << "Program was execute";
    }
    else
    {
     cout << "Condition was false therefore if condition progarm was not run " << endl
             << endl;
        cout << " else statement program was execute";
    }

    return 0;
}



Output -

If the entered integer in equal to the condition they it run 
12
Condition was false therefore if condition progarm was not run 

 else statement program was execute

3. if-else-if statement -
 In this statement we use if for many if else statement was there if one is false then it check second and if second is false then it go to next statement and this step goes on .

syntax -

if(condition)
{
// code in the condition
}
else if (condition)
{
//code in the condition
}
else if (condition)
{
//code in the condition
}
.
.
.
.

else 
{
...
}


Program -
 // if-else-if statement

#include <iostream>
using namespace std;

int main()
{
    int a;
    cout << "If the entered integer in equal to the condition they it run " << endl;
    cin >> a;
    if (a <= 6)
    {
        cout << "Program was execute";
    }
    else if (a>=12)
    {
        cout << "second Condition was execute " << endl;
    
    }
    else
    {
        cout << "else Condition was execute " << endl;
    
    }

    return 0;
}


Output -

If the entered integer in equal to the condition they it run 
32
second Condition was execute 

While loop -

while loop use for run a specific code many time in a program then we use while loop and run the program many times .

syntax -
while(condition)
{
// code 
}

Program -
// while loop in c language 
#include <iostream>
using namespace std;

int main()
{
    int i=1;
    while(i<=7)
    {
        cout<<i<<"-"<<"this is a number "<<i<<endl;
        i++;
    }
    return 0;
}




Output -

1-this is a number 1
2-this is a number 2
3-this is a number 3
4-this is a number 4
5-this is a number 5
6-this is a number 6
7-this is a number 7


Do-While loop ->

// Do-while loop in c language 
#include <iostream>
using namespace std;

int main()
{
    int i=1;
    do
    {
        cout<<i<<"-"<<"this is a number "<<i<<endl;
        i++;
    }while(i<=7);

    return 0;
}


Output -

1-this is a number 1
2-this is a number 2
3-this is a number 3
4-this is a number 4
5-this is a number 5
6-this is a number 6
7-this is a number 7

Funcation in c++ programming example in detail

Friend Funcation- 1. Adding to complex number in friend function #include<iostream> using namespace std; class container { float a,b; public: void get() { cout<<endl<<"Enter value for A="; cin>>a; cout<<endl<<"Enter value for B="; cin>>b; } void disp() { cout<<endl<<a; cout<<endl<<b; } friend container addition(container,container); }; container addition(container X,container y) { container Z; Z.a=X.a+y.a; Z.b=X.b+y.b; return Z; } int main() { container P,Q,R; P.get(); P.disp(); Q.get(); Q.disp(); R=addition(P,Q); R.disp(); return 0; } Output - Enter value for A=12 Enter value for B=12 12 12 Enter value for A=1 Enter value for B=1 1 1 13 13 2.  If class one is friend function of two it not means that two is friend functio...

C++ programming tutorial 5

 Call by value or reference - There are two type in function call by value or call by reference in it we pass the value in call by value we pass value and in call by reference we pass the reference of the value . Call by value in C++ Programming language  :- In call by value we pass the variable or say argument and then it used by function which we made so see the code given below  Syntax - #include <iostream > using namespace std; // making function  void fun_name(int a, int b) { ... } int main() { //calling function  fun_name(int n,int n1); return 0; } Code -  // function call by value in C++ programming #include <iostream> using namespace std; // call by value in function declaration void container(int a, int b); int main() {   int x,y;   cout<<"Enter the value of x :"<<endl;   cin>>x;   cout<<"Enter the value of y :"<<endl;   cin>>y;   // here we passing the value as argume...
