C subtract programming for beginners

C Subtract Programming for beginners

In this example of C tutorial, we will take two integers from the user using scanf() function and print the subtracted value in the console/screen.

Write a C program to print the subtracted value of two numbers.

Program:

================================

//Program to add two numbers after taking input from user #include<stdio.h> int main(void) { int number1, number2, sub;//defining the various variables printf("Enter the first and second number\n");//The first line that is displayed on the screen scanf("%d%d",&number1,&number2);//Taking the input of two numbers sub = number1-number2;//Calculating the subtract value printf("The subtracted value is %d",sub);//Printing the subtract value on the screen return 0; }

================================

Output:

================================

Enter the first and second number

50 45

The sum is 5

================================

Explanation of the program:

# : If any line start with #, it is a pre-process only that line. Special symbol (#) to indicate the pre-processor directive.

include : pre-processor directive. I include important file in the C program.

stdio.h : This file contains functions such as printf() and scanf() to print in the screen and taking input from the user.

main() : The C program execution starts from this line. The main() function is called by the operating system (O/S).

int : It is an Integer data type.

number1/ number2/sub : They are the variable to store integer data type. Just like the bucket is to store water, this variable is to store integer numbers.

scanf() : It is a function defined in the stdio.h header file, to take the date from the user.

%d : It is the format specifier for the Integer data type.

& : Address of any variable in the memory.

printf() : It is a function defined in the stdio.h header file, to print or send output to the screen/consol.

return 0 : This statement is to Exit the program. It tells the operating system (O/S) that the program has run successfully, as 0 means success. In place of 0 we can use any number like 1, 2,… but the general convention is to write 0.
