{
int a,b;
a = 20;
b = 10;
printf("a = %d , b = %d",a,b);
return 0;
}

4. Problem 2: Add two Number & Show output
#include<stdio.h>
int main()
{
int a,b,c;
a = 20;
b = 10;
c = a + b;
printf("Summation of a + b = %d n",c);
return 0;
}
 Try yourself : c = a-b , c = a*b , c = a/b

5. Introduce scanf():
• To give input to a program from keyboard we
need to use scanf() function.
• It is a built-in function of C.
• The definition of scanf() function given in stdio.h
header file.
• So if you use scanf() function into your program,
you should #include<stdio.h> header file.

6. Problem 3: Add two Number & Show output
#include<stdio.h>
int main()
{
int a,b,c;
printf("Enter two numbers: ");
scanf("%d %d",&a,&b);
c = a + b;
printf("n Summation of a + b = %d n",c);
return 0;
}
 Try yourself : c = a-b , c = a*b , c = a/b
