Some programs related to For Loop in c prgramming


1- Wap to print all the number from 1 to 10 ?


#include <stdio.h>
#include<conio.h>
void main()

{
      int i;

   clrscr();

for(i=1; i<=10; i++)

 { 
     printf(“n%d” &i);
}

getch();

}

2- Wap to print all the number from 1 to 20 ?

#include <stdio.h>
#include<conio.h>
void main()
{
      Int i;

    clrscr();

for(i=1; i<=20; i++)
 { 
     printf(“n%d” &i);
 }
getch();

}

3- Wap to print all the number from 5 to 15 ?

#include <stdio.h>
#include<conio.h>
void main()
{
      int i;
    clrscr();

 for(i=5; i<=15; i++)
 { 
     printf(“n%d” &i);
}
getch();

}

4- Wap to accept the number from user that is  n  then print all number from 1 to n?

#include <stdio.h>
#include<conio.h>
void main()
{
     int i;
   clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for(i=1; i<=n; i++)
 { 
     printf(“n%d” &i);
}
getch();

}

5- Wap to print the sum  of all the number from 1 to 5 ?

#include <stdio.h>
#include<conio.h>
void main()
{
      int I, sum=0;
      clrscr();

for(i=1; i<=5; i++)
 { 
     sum=sum+i;
}
printf(“sum is %d”, sum);

getch();

}

6- Wap to accept a number from user then calculate the sum of all the number from 1 to n and print a number.

#include <stdio.h>
#include<conio.h>
void main()
{
      int i, sum=0;
      clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for(i=1; i<=n; i++)
 { 
    sum=sum+i;
}

printf(“sum is %d”, sum);

getch();
}

7- Wap to accept a number from user then print all the even number from 1 to n.

#include <stdio.h>
#include<conio.h>
void main()
{
      int  n, i;
     clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for(i=2; i<=n; i++)
 { 
printf(“\n%d”, i);

i=i+1;
}

getch();
}

8- Wap to accept a number from user then print sum of all the even number between 1 to n?
#include <stdio.h>
#include<conio.h>
void main()
{
      int  n, i, sum=0;
     clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for(i=1; i<=n; i++)

   if (i%2==0)
 { 
  sum=sum+i;
 }

printf(sum  is %d”, sum);

getch();
}

9-Wap to accept a number from user then print the sum of all the number from 1 to n and average of number from 1 to n?
  
#include <stdio.h>
#include<conio.h>
void main()
{
      int  n, i, sum=0,avg;
     clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for(i=1; i<=n; i++)

if (i%2==0)
 { 
   sum=sum+i;
}

if=sum/n;
printf(“sum  of number is %d”, sum);
printf(“average  is %d”, avg);

getch();
}

10- Wap to print all the number from 1 to 10?

#include <stdio.h>
#include<conio.h>
void main()
{
     int i;
    clrscr();

for (i=10; i>=i; i--)
{
printf(“%d”, i);
}
getch();

}

11- Wap to accept a number from user that is n then print all the number from n to 1?

#include <stdio.h>
#include<conio.h>
void main()
{
int  n,i;
clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for (i=n; i>=1; i--)

{
printf(“%d”, i);
}
getch();
}




12- Wap to accept a number from user that is n then print all the  odd number from n to 1?


#include <stdio.h>
#include<conio.h>
void main()
{
int  n,i;
clrscr();

printf(“enter a number”);
scan(“%d”, &n);

for (i=n; i>=1; i--)
{
printf(“%d”, i);
i=i-2;
}
getch();
}
