C Program to Print Your Own Name - printf, scanf, puts, fputs & write
Print Name Using printf()
#include <stdio.h>
int main() {
printf("John Doe\n");
return 0;
}John Doe
The simplest way to display your name is by supplying a string literal to printf(). When executed, this prints the exact characters you provide.
Print Name After User Input
#include <stdio.h>
int main() {
char name[50];
printf("Enter your name: ");
scanf("%49s", name);
printf("Your name is %s\n", name);
return 0;
}Enter your name: Alice
Your name is Alice
This version allocates an array of characters, prompts for input and captures a single word using scanf(). The name is then printed back with another call to printf().
Print Name Using puts()
#include <stdio.h>
int main() {
puts("John Doe");
return 0;
}John Doe
The puts() function, defined in <stdio.h>, outputs the given string followed by a newline automatically.
Print Name Using fputs()
#include <stdio.h>
int main() {
fputs("John Doe", stdout);
return 0;
}John Doe
fputs() writes a string to the specified file stream; when the stream is stdout it produces output on the screen.
Print Name Using write()
#include <unistd.h>
int main() {
write(1, "John Doe", 9);
return 0;
}John Doe
The write() function is a low‑level system call that writes raw bytes to a file descriptor; 1 corresponds to the standard output file descriptor.
There are many ways to print a name in C. Passing a string literal to printf() is the most direct approach. For interactive programs you can store the user’s name in a character array using scanf() and then echo it back. The puts() function prints a string followed by a newline, while fputs() writes a string to a specified stream. Finally, the write() system call writes a given number of bytes to a file descriptor such as standard output.
