program 9. Write a program accept three numbers check whether first number is between other two.

#include<stdio.h>

void main()

{

    int a,b,c;

    printf("Enter three numbers:");

    scanf("%d%d%d",&a,&b,&c);

    if(a<c && b<a)

    {

        printf("%d is between %d to %d \n",a,b,c);

    }

    else

    {

        printf("%d is not between %d to %d",a,b,c);

    }

}

Output

Enter three numbers:8 1 9

8 is between 1 to 9

 program 8: Accept a number check whether number is even.

#include<stdio.h>

int main()

{

                int num;

                printf("\nEnter  Number:");

                scanf("%d", &num);

                if(num%2==0)

                {

                        printf("\n%d is Even",num);

                }

                else

                {

                        printf("\n%d is Odd",num);

                }

}

 Output    

[root@localhost Desktop]# cd ~/Desktop

[root@localhost Desktop]# gcc even.c

[root@localhost Desktop]#  ./a.out

Enter  Number:8

8 is Even

Program 7: Accept two integer from the user and interchange them display interchange number.

#include<stdio.h>

void main()

{

int x,y,temp;

printf("Enter two numbers to interchange:");

scanf("%d%d",&x,&y);

temp=x;

x=y;

y=temp;

printf("\nInterchanged numbers are %d and %d",x,y);

}

Output

[root@dhcppc16 ~]# cd ~/Desktop

[root@dhcppc16 Desktop]# gcc tm.c

[root@dhcppc16 Desktop]# ./a.out

Enter two numbers to interchange:9 12

Interchanged numbers are 12 and 9

Program 6: Accept the x and y coordinates of two points and compute the distance between the two points.

#include<stdio.h>

#include<math.h>

int main()

{

float x1,x2,y1,y2,compute,distance;

printf("\nEnter values of x1 and y1:");

scanf("%d%d",&x1,&y1);

printf("\nEnter values of x2 and y2:");

scanf("%d%d",&x2,&y2);

compute=((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1));

distance=sqrt(compute);

printf("\nDistance=%f",distance);

}

 Output

[root@localhost ~]# cd ~/Desktop

[root@localhost Desktop]# gcc  distance.c

[root@localhost Desktop]# ./a.out

Enter values of x1 and y1:5 4

Enter values of x2 and y2:9 8

distance=5.656854

Program 5: Accept a character from the keyboard and display its previous and next character.

#include<stdio.h>

void main()

{

    char ch;

    printf("Enter Character:");

    scanf("%c",&ch);

    printf("\nPrevious character of  %c is %c",ch,ch-1);

    printf("\nNext character of %c is %c",ch,ch+1);

}

Output

Enter Character: r

Previous character of r is q

Next character of r is s ✔

Program 4: Accept a character from the user and display its ascii value.

#include<stdio.h>

void main()

{

char ch;

printf("Enter Character:");

scanf("%c",&ch);

printf("\nThe ASCII value of  %c is %d",ch,ch);

}

Output

Enter The Character: m

The ASCII value of  b is  98 ✔
