C-42 : Read values from keyboard for calculations

Read values from keyboard for calculations . And see how scanf() works.

Refer Simple Calculations also.

#include<stdio.h> #include<conio.h> main()      {       clrscr();       int x,y,z;       printf("Enter a value of x:");       scanf("%d",&x);       printf("Enter a value for y:");       scanf("%d",&y);       z=x*y;       printf("z=x*y=%d\n",z);       getch();       return 0;      }

Output :

Enter a value of x: 3Enter a value of y: 4
z=x*y=12

C-41: Simple Calculations

Elementary operations with small integers:

Refer Find Sum also.

#include<stdio.h> #include<conio.h> main()       {       clrscr();       printf("\n\t\n\t");       printf("x=%d,y=%d\n",x,y);       z=x-y;       printf("z=x-y=%d\n",z);       z=x*y;       printf("z=x*y=%d\n",z);       z=x/y;       printf("z=x/y=%d\n",z);       z=y/x;       printf("z=y/x=%d\n",z);       z=x%y;       printf("z=x%%y=%d\n",z);       z=y%x;       printf("z=y%%x=%d\n",z);       getch();       }

Output :x=5,y=7
z=x-y=-2
z=x*y=35
z=x/y=0
z=y/x=1
z=x%y=5
z=y%x=2

C-40 : Check your Progress -1

Refer

1.  My first C Program 
2.  Example for Nested IF
3. Example of Escape Sequence (\n)

Then , try to answer the following questions :

1. Do you think comments can be nested , that is , can you have a comment with in a comment? Write a program with a nested comment and see if you can compile it.
2. Write a C language program that gives for its output :    \* This is a C Comment*\
3. Debug the following program :

#include<stdio.h>
#include<conio.h>
void main{}
(
            print("print this\m"\*very easy*\).
)
