Write these programs using C++

1. Using while loop display the following a)1 2 3 4 56789 10 b) 10 9 8 7 65 4 321 2. Using do while loop calculate your average income in a week 3. Using for loop display the following a) 4 8 12 16 20 24 b) 5 10 15 20 25 30

Solution

1)a)//print numbers from 1 to 10 using while loop

//preprocessor directives

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

//initialize i value as 1

int i=1;

//loop till i value becomes equal to 1

while(i<=10)

{

//print value of i

cout<<i<<\"\\t\";

//incrment i

i++;

}

getch();

}

1.b)//print numbers from 10 to 1 using while loop

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

int i=10;

//iterate till i value becomes equal to 1 from 10

while(i>=1)

{

//print value of i

cout<<i<<\"\\t\";

//decrement value of i

i--;

}

getch();

}

2.//calculate average income using do while loop

//preprocessor directives

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

int i=1,sum_income=0,average_income=0;

do

{

//enter day based income

cout<<\"Enter the income earned in \\t\"<< i <<\"\\t day\ \";

cin>>day_income;

//calculation of total income earned in a week

sum_income=sum_income+day_income;

}while(i<=7);

//calculation of average income

average_income=(sum_income/i);

cout<<\"\ \"<<average_income<<\"\ \";

getch();

}

3.a) using for loop print numbers 4 8 12 16 20 24

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

int i;

//iterate till i value becomes equal to 24 from 4

for(i=4;i<=24;)

{

//print value of i

cout<<i<<\"\\t\";

//increment value of i by 4

i=i+4;

}

getch();

}

3.b) using for loop print numbers 5 10 15 20 25 30

//preprocessor directives

#include<iostream>

#include<conio.h>

using namespace std;

void main()

{

int i;

//iterate till i value becomes equal to 30 from 5

for(i=5;i<=30;)

{

//print value of i

cout<<i<<\"\\t\";

//increment value of i by 5

i=i+5;

}

getch();

}
