In C language, print out 'Hello World' without using any header file
Usually, we use header files in C/C language to access built-in functions, such as int, char, and string functions. The function printf() is also a built-in function, which is declared in the "stdio.h" header file and is used to print any type of data on the console.
The following is a sample code for printing in C language without using a header file:
Sample code
int printf(const char *text, ...); int main() { printf( "Hello World" ); return 0; }
Output
Hello World
int printf(const char *text, ...);
