// ADDITION OF TWO NUMBER: 2 Methods

1. With the help of scanf() function
2. without scanf() function

#include<stdio.h>

#include<conio.h>

void main()

{

float a,b,c;

clrscr();

a=10.2;

b=5.3;

c=a+b;

printf("Sum of two Numbers=%f" ,c);

getch();

}

Output:

Sum of two Numbers=15.5

2. With the help of scanf() Function:

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c;

clrscr();

printf(" Enter the value of a and b:/n");

scanf("%d%d",&a,&b);

c=a+b;

printf("Addition of Two Numbers=%d" , c);

getch();

}

Output:

Enter the value of a and b:

50
