Answer:
we will write two C programs to display Hello World on the screen. In the first program we are displaying the message using printf function and in the second program we are calling a user defined function and that function displays the Hello World message on the screen.
Example 1: Displaying Hello World
#include <stdio.h>
int main()
{
/* printf function displays the content that is
* passed between the double quotes.
*/
printf("Hello World");
return 0;
}
Output:
Hello World
1. #include <stdio.h> – This statement tells compiler to include this stdio.h file in the program. This is a standard input output file that contains the definitions of common input output functions such as scanf() and printf(). In the above program we are using printf() function.
2. int main() – Here main() is the function name and int is the return type of this function. Every C program must have this function because the execution of program begins with the main() function. The 0 return value of this function represents successful execution of program while the return value 1 represents the unsuccessful execution of program. This is the reason we have return 0; statement at the end of this main function.
3. printf("Hello World"); – This function displays the content within double quotes as it is on the screen.
4. return 0; – As mentioned above, the value 0 means successful execution of main() function.
