How to display the value of output variable in c language

How to display the value of the output variable in C language: First create a C language code sample file; then use printf() in C language to output multiple variable values.

The operating environment of this article: Windows 7 system, version C11, Dell G3 computer.

C language displays the value of a variable, which is also the output variable value. In C language, you can use printf() to output multiple variable values.

Below we will introduce to you through specific code examples how to display output variable values ​​in C language.

The code example is as follows:

#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 = &#39;W&#39;;
    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;
}

The result output is as follows:

In the above code, the specified variable is first Declaration:

int Declare the a and b variables as integer variables,

long Declare the ax variable as long integer type.

short Declare s as short integer type,

float Declare x variable as floating point type,

double declares the dx variable as a double precision real variable,

char declares the c variable as a character,

unsigned long declares the ux variable Is an unsigned long integer.

Finally, the specified variable value is output through the printf() function. The calling format of the printf() function is:

printf("<格式化字符串>", <参量表>);

This article is about displaying variable values ​​in c language That is, the specific method of outputting variable values ​​is introduced, which is easy to understand. I hope it will be helpful to friends in need!
