[Tutorial 7] 1.Write a program that subtracts the value 15 from 87 and displays the result, together with an appropriate message, at the terminal.

#include <stdio.h>
int main(void)
{
int sum;

/* COMPUTE RESULT */
sum = 87 - 15;

/* DISPLAY RESULTS */
printf ("The answer is %i \n", sum);

return 0;
}
This C program calculates the result of subtracting 15 from 87 and then displays the result as "The answer is 72" using the `printf` function.

Output:
The answer is 72

Compilation process in c

Image
   What is a compilation?        C is a programming language that converts source code into object code or machine code. The conversion process has four steps: Pre-processing, Compiling, Assembling, and Linking.      The preprocessor eliminates all the comments from the source code and carries out the preprocessor directives. For instance, it substitutes the directive <stdio.h> with the contents of the 'stdio.h' file.       The following are the phases through which our program passes before being transformed into an executable form:         Preprocessor         Compiler         Assembler         Linker Preprocessor A source code file is a text file that contains instructions written in the C programming language. The file name has a ".c" extension to indicate its format. Before compiling the source code, a preprocessor analyzes and modifies i...
