Differences of two number for beginners with basic..

Subtraction of two number for beginners with basic.

According to mathematics….

If a=50 and b=20 then differences = a-b so, 50-20 then answer is ’30’

In this programme initially  you can take number before run. example a=10, b=20,. This programme is only for basic and for beginners.

Some important symbols used in code.

1. #include<stdio.h>
2. #include<conio.h>
3. void main()
4. {
5. int a, b, c;
6. clrscr();
7. printf(“The difference of two number\n”)
8. a=100;
9. b=25;
10. c=a-b;
11. printf(“n1 %d – n2 %d = %d”, a, b, c);
12. getch();
13. }

Inputs..

If a=100 and b=25 then.

Results..

Subraction = ’75’
