C-Programmes

1.Find Multiplication Of entered Number :

void main()
{
int i,num;
clrscr();
printf("enter the number\n");
scanf("%d",&num);
i=1;
while(i<=10)
{
printf("%d*%d=%d",num,i,num*i);
i++;
printf("\n");
}
getch();
}



2.WAP 2 Print Even Numbers Between 1-100 :

main()
{
int num=100;
clrscr();
printf("The even numbers within 100 are");
while(num!=1)
{
num=num/2;
printf("%d\t",num);
}
getch();
}


3.SWITCH Case:

void main()
{
char choice;
int a,b,temp;
clrscr();
printf("enter two integer\n");
scanf("%d%d",&a,&b);
printf("\t+. Add\n \t-.Subtraction\n \t*.multiply\n");
printf("\n\t Enter your choice\n");
scanf("%s",&choice);
switch(choice)
{
case '+':
    temp=a+b;
    printf("sum=%d",temp);
    break;
case '-':
    temp=a-b;
    printf("substraction =%d",temp);
    break;
case '*':
    temp=a*b;
    printf("multiply =%d",temp);
    break;
default:
    printf("invalid choice\n");
    }
    getch();
    }
