Write a program to print sum, subtract, multiply, division of two number

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c;
clrscr();
printf("\tEnter the two number \n\n\b ");// Escape Sequences
scanf("%d %d",&a, &b);
c=a+b;
printf("\n sum of two number = %d ",c);
c=a-b;
printf("\n Subtraction of two number = %d ",c);
c=a*b;
printf("\n Multiplication of two number = %d ",c);
c=a/b;
printf("\n Division of two number = %d ",c);
getch();
}
Output:-
Enter the two number
 7
8
 sum of two number = 15
 Subtraction of two number = -1
 Multiplication of two number = 56
 Division of two number = 0

Write a program to print sum of two number using increment operator

#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,c;
clrscr();
printf("Enter the two number ");
scanf("%d %d",&a, &b);
c=a+b;
printf("\n sum of two number = %d ",c);
c++; //Increment operator
printf("\n Increment of two number = %d \t ",c);// Escape Sequences
getch();
}
Output:-
Enter the two number 6
8

 sum of two number = 14
 Increment of two number = 15
