char userInput [3] ;
int difference = strcmp(userInput, "yes");

Given that userInput is set to "yes", what is the value of difference?

Enter a number below:

How do we compare two strings?

• strcmp(str1, str2)

• str1 = str2

• str1 == str2

What is a declaration?

• Saying what a variable or function is equal to

• Saying that a variable or function exists

• An error statement

Given the following :

int age = 12;

How do we print the variable age?

• print("%d", age);

• printf("%d", age);

• printf("%s", age);

• printf(age);

Given the following string declaration:

char userInput[30];

How do we get input and store it in userInput?

• fscanf(stdin, "%d", userInput);

• fscanf(stdin, userInput);

• input(stdin, userInput);

• fscanf(stdin, "%s", userInput);

How do end the program programmatically?

Hint: Programmatically means through the c code

• exit(0);

• break;

• end;

• exit;

Define a boolean type variable called isUgly and set it equal to true

Library for using boolean types

• #include <stdbool.h>

• #include <string.h>

• #include <stdlib.h>

• #include <stdio.h>

Library for using strcmp and other string functions

• #include <stdbool.h>

• #include <string.h>

• #include <stdlib.h>

• #include <stdio.h>

This header imports a library for defining four variable types (e.g size_t), several macros, and various functions like exit(0) for performing general functions.

• #include <stdbool.h>

• #include <string.h>

• #include <stdlib.h>

• #include <stdio.h>
