    C: Strings - Storing Strings


    (Page 2 of 6 )

    In C, you store strings in arrays, with each letter of the string going into a separate element in the array. Let's say we want to store a name in an array. Let's say the name is really cool and regal...something like: James. Here is how we would create the array to store the value and then access the array to print it out:


    #include <stdio.h>


    int main ()

    {

    char name[10]="James";

    printf (name);

     

    return(0);

    }

    Here we create an array named “name” and store the string “James” inside of it. Then we use the printf() function to print out the stored value, resulting in:

      James

    Storing Strings from User Input

    In the following code we will ask the user to enter their first name and then print that name to the screen:


    #include <stdio.h>

    int main ()

    {

    char name[10];

    printf("Enter your first name ");

    gets_s (name);

    printf("Your name is %s", name);

    return(0);

    }

    This program creates an array called “name”. It then prints some text asking the user to input their first name. Then it uses the get_s() function to store the data the user enters into the name array. Lastly we print out the value inside name using the printf() function and the %s placeholder.

    Note that when assigning the amount of elements in the array, be sure to include one extra for the null terminator (o) that C inserts at the end.
