read a document in c getting name from console

To read a document in C and get a name from the console, you can use the scanf function to read input from the user. Here's an example code snippet:

#include <stdio.h>

int main() {
    char name[50];

    printf("Enter your name: ");
    scanf("%s", name);

    printf("Hello, %s!\n", name);

    return 0;
}

In this code, we declare a character array name with a size of 50 to store the name entered by the user. Then, we use printf to prompt the user to enter their name. The %s format specifier is used with scanf to read a string (sequence of characters) from the user and store it in the name array. Finally, we use printf to display a greeting message that includes the entered name.

Note that in this example, the assumption is that the user will enter a single word as the name. If you want to read a full name with spaces, you can use the %[^\n] format specifier with scanf instead, like this:

scanf(" %[^\n]", name);

This will read the entire line of input until a newline character (\n) is encountered, allowing you to capture a name with spaces.

Remember to include the necessary header file stdio.h for input/output operations, and to compile and run the code to see the desired output.
