Program 47 - CSU1128 - CSE 2026 - Shoolini University

Program to take input of name entered by the user through a function block and output it

Explanation

The program takes the user's name as input through a function and then outputs it.

Header

The code begins with including the standard input-output header file and string manipulation header file using #include <stdio.h> and #include <string.h>.

Function Declaration

The program declares a function getName to get the user's name:

void getName(char *name);: Declares the function with a character pointer name as a parameter.

Variable Declaration

The main() function is defined, and a variable is declared:

char name[100]: Array to hold the user's name.

Program Description

The program prints a description message for the user to understand its functionality.

Function Call

The program calls the getName function to get the user's name:

getName(name);: Calls the function with name as an argument.

Output Result

The program prints the name stored in the array:

printf("Your name is: %s\n", name);: Prints the user's name.

Function Definition

The program defines the getName function:

void getName(char *name): Defines the function with a character pointer name as a parameter.
printf("Enter your full name: ");: Prompts the user to enter their name.
fgets(name, 100, stdin);: Reads the name including spaces and stores it in the array name.
name[strcspn(name, "\n")] = 0;: Removes the trailing newline character from the string.

Program End

The program ends with return 0; to indicate successful execution.
