I'm learning C language and stuck with a question as follows: #include #include void main() { short int a=5; clrscr(); printf("%d"+1,a); getch(); } Please explain what is the output of this program. Thanks .
Predict the output of following C programs. Question 1 C #include int main() { int arr[] = {}; printf("%d", sizeof(arr)); return 0; } Output: 0 C (or C++) allows arrays of size 0. When an array is declared with empty initialization list, size of the array becomes 0. Questio
Output: x=10 y=10 z=10. Description: *y is a pointer variable whereas **z is a pointer to a pointer variable. *y gives the value at the address it holds and **z searches twice i.e., it first takes the value at the address it holds and then gives the value at that address.

Line 2: A blank line. C ignores white space. But we use it to make the code more readable. Line 3: Another thing that always appear in a C program is main().This is called a function.Any code inside its curly brackets {} will be executed.. Line 4: printf() is a function used to output/print text to the screen. In our example, it will output "Hello World!".
Simple C program explained.Why #inclde, int main(), return 0. Hello World Program. ... If we use #include in your c program, it will include stdio.h file into our source program which has the information for all input, output related functions. ... Why int main()? As we discussed earlier, the main function is the starting ...
Example. Let's look at an example of how to use #include directives in your C program. In the following example, we are using the #include directive to include the stdio.h header file which is required to use the printf standard C library function in your application. /* Example using #include directive by TechOnTheNet.com */ #include int main() { /* * Output "TechOnTheNet began in ...
C stdio Functions. The header provides a variety of functions for input, output and file handling. A list of all stdio functions can be found in the table below: Function Description; fclose() Closes a file: feof() Returns a true value when the position indicator has reached the end of the file:
The macro function CUBE(x) (x*x*x) calculates the cubic value of given number(Eg: 10 3.). Step 1: int a, b=3; The variable a and b are declared as an integer type and varaible b id initialized to 3.. Step 2: a = CUBE(b++); becomes => a = b++ * b++ * b++; => a = 3 * 3 * 3; Here we are using post-increement operator, so the 3 is not incremented in this statement.
Now as we need to include stdio.h using #include in order to use printf() function similarly, we also need to include the header file process.h as #include "process.h". The " " instructs the preprocessor to look into the present folder or the standard folder of all header files, if not found in the present folder.
