In this Sum and Difference of Two Numbers problem solution in C Programming Your task is to take two numbers of int data type, two numbers of float data type as input and output their sum:

1. Declare 4 variables: two of type int and two of type float.
2. Read 2 lines of input from stdin (according to the sequence given in the 'Input Format' section below) and initialize your 4  variables.
3. Use the + and - operator to perform the following operations:
4. Print the sum and difference of two int variables on a new line.
5. Print the sum and difference of two float variables rounded to one decimal place on a new line.

```#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main()
{
int a,b,sum=0,sub=0;
float c,d,s=0,su=0;
scanf("%d%d",&a,&b);
sum= a+b;
sub=a-b;
printf("%d %d\n",sum,sub);
scanf("%f%f",&c,&d);
s=c+d;
su=c-d;
printf("%0.1f %0.1f",s,su);

return 0;
}```

## Second solution

```#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>

int main()
{
int a, b;
float c, d;
scanf("%d %d", &a, &b);
scanf("%f %f", &c, &d);

printf("%d %d\n%.1f %.1f", a+b, a-b, c+d, c-d);

return 0;
}```
