Little help here please
Create a program that performs the following functions: uses character arrays to read a user’s name from standard input, tells the user how many characters are in his or her name, and displays the user’s name in uppercase.
Here's a step-by-step guide to create a program that fulfills the given requirements:
Step 1: Include the necessary header files:
```c++
#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;
```
Step 2: Define the main function:
```c++
int main() {
// ...
return 0;
}
```
Step 3: Declare a character array to store the user's name:
```c++
char name[100];
```
Step 4: Read the user's name from standard input:
```c++
cout << "Enter your name: ";
cin.getline(name, 100);
```
Step 5: Determine the number of characters in the name using the `strlen` function:
```c++
int numChars = strlen(name);
```
Step 6: Print the number of characters to the user:
```c++
cout << "The number of characters in your name is: " << numChars << endl;
```
Step 7: Convert the name to uppercase using the `toupper` function:
```c++
for (int i = 0; i < numChars; i++) {
name[i] = toupper(name[i]);
}
```
Step 8: Print the uppercase name to the user:
```c++
cout << "Your name in uppercase is: " << name << endl;
```
Step 9: Compile and run the program.
Here's the complete code:
```c++
#include <iostream>
#include <cstring>
#include <cctype>
using namespace std;
int main() {
char name[100];
cout << "Enter your name: ";
cin.getline(name, 100);
int numChars = strlen(name);
cout << "The number of characters in your name is: " << numChars << endl;
for (int i = 0; i < numChars; i++) {
name[i] = toupper(name[i]);
}
cout << "Your name in uppercase is: " << name << endl;
return 0;
}
```
This program prompts the user to enter their name, counts the number of characters in the name, and displays the name in uppercase.
To create a program that reads a user's name, calculates the number of characters in the name, and displays the name in uppercase, you can follow these steps:
1. Start by including the necessary header files, typically `stdio.h` for input/output functions and `ctype.h` for character manipulations.
2. Declare a character array that can hold the user's name. For example, you can declare an array of size 100 to handle most names.
```c
#define MAX_NAME_SIZE 100
char name[MAX_NAME_SIZE];
```
3. Use the `printf` function to prompt the user to enter their name:
```c
printf("Enter your name: ");
```
4. Use the `fgets` function to read the user's name from standard input. This function will read a whole line of input, including spaces, and store it in the `name` array.
```c
fgets(name, sizeof(name), stdin);
```
5. To calculate the number of characters in the name, you can use the `strlen` function from the `string.h` library.
```c
#include <string.h>
int nameLength = strlen(name);
printf("Number of characters in your name: %d\n", nameLength);
```
6. To display the user's name in uppercase, you can iterate over each character in the `name` array and convert it to uppercase using the `toupper` function from the `ctype.h` library.
```c
#include <ctype.h>
for (int i = 0; i < nameLength; i++) {
name[i] = toupper(name[i]);
}
```
7. Finally, use the `printf` function to display the uppercase name.
```c
printf("Your name in uppercase: %s\n", name);
```
That's it! Your program will now read the user's name, calculate the number of characters, and display the uppercase name. Don't forget to include the necessary header files and compile the program using a C compiler.
