C Exercises: Display multiple variables

C Basic Declarations and Expressions: Exercise-7 with Solution

Write a C program to display following variables.
a+ c, x + c,dx + x, ((int) dx) + ax, a + x, s + b, ax + b, s + c, ax + c, ax + ux
Variable declaration :
int a = 125, b = 12345;
long ax = 1234567890;
short s = 4043;
float x = 2.13459;
double dx = 1.1415927;
char c = 'W';
unsigned long ux = 2541567890;

C Code:

#include <stdio.h> 
int main()
{
    int a = 125, b = 12345;
    long ax = 1234567890;
    short s = 4043;
    float x = 2.13459;
    double dx = 1.1415927;
    char c = 'W';
    unsigned long ux = 2541567890;

    printf("a + c =  %d\n", a + c);
    printf("x + c = %f\n", x + c);
    printf("dx + x = %f\n", dx + x);
    printf("((int) dx) + ax =  %ld\n", ((int) dx) + ax);
    printf("a + x = %f\n", a + x);
    printf("s + b =  %d\n", s + b);
    printf("ax + b = %ld\n", ax + b);
    printf("s + c =  %hd\n", s + c);
    printf("ax + c = %ld\n", ax + c);
    printf("ax + ux = %lu\n", ax + ux);

    return 0;
}

Sample Output:

a + c =  212                                                           
x + c = 89.134590                                                      
dx + x = 3.276183                                                      
((int) dx) + ax =  1234567891                                          
a + x = 127.134590                                                     
s + b =  16388                                                         
ax + b = 1234580235                                                    
s + c =  4130                                                          
ax + c = 1234567977                                                    
ax + ux = 3776135780

Solution

#include <stdio.h> 
int main()
{
    int a = 125, b = 12345;
    long ax = 1234567890;
    short s = 4043;
    float x = 2.13459;
    double dx = 1.1415927;
    char c = 'W';
    unsigned long ux = 2541567890;

    printf("a + c =  %d\n", a + c);
    printf("x + c = %f\n", x + c);
    printf("dx + x = %f\n", dx + x);
    printf("((int) dx) + ax =  %ld\n", ((int) dx) + ax);
    printf("a + x = %f\n", a + x);
    printf("s + b =  %d\n", s + b);
    printf("ax + b = %ld\n", ax + b);
    printf("s + c =  %hd\n", s + c);
    printf("ax + c = %ld\n", ax + c);
    printf("ax + ux = %lu\n", ax + ux);

    return 0;
