Program to store 5 names entered by the user in an array and display them

Explanation

The program stores a specified number of names entered by the user in an array and displays them.

Header

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

Variable Declaration

The main() function is defined, and several variables are declared:

  • int n: Stores the number of names the user wants to provide.
  • char names[n][100]: Declares a 2D array of characters to store the names. Each name can have up to 99 characters plus the null terminator.

Program Description

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

User Input

The user is prompted to enter the number of names and the names themselves:

  • printf("Enter the number of names you want to provide: ");: Prompts the user to enter the number of names.
  • scanf("%d", &n);: Reads the number of names and stores it in n.
  • char names[n][100];: Declares a 2D array with n rows and 100 columns.
  • for (int i = 0; i < n; i++): Loop to read each name.
  • printf("Enter full name %d: ", i + 1);: Prompts the user to enter a name.
  • fgets(names[i], sizeof(names[i]), stdin);: Reads each name including spaces and stores it in the array.

Display Names

The program prints the names stored in the array:

  • for (int i = 0; i < n; i++): Loop to print each name.
  • printf("Full name %d: %s", i + 1, names[i]);: Prints each name with its corresponding number.

Program End

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

Note

There is a potential issue with reading the names due to the leftover newline character from the previous scanf call. Find a way to fix this! You can add getchar(); after scanf to consume the newline character but will it help and work in vscode? Thats for you to decide!

scanf("%d", &n);
getchar(); // Consume the newline character
