Assignment ➡️

Variables can be be given or assigned a value, by doing

var_name = value;

where,

var_name is the name of the variable,

value is the value you are assigning to the variable.

This overwrites the existing value of a variable.

The assigned value has to be of the same type as the variable.

Good

int some_int_var;
float some_float_var;
char some_char_var;
char* some_string_var;

some_int_var = 10;
some_float_var = 0.5;
some_char_var = 'a';
some_string_var = "hello there!";

Bad

int some_int_var;
char some_char_var;

// Integer variables can't store a float!
some_int_var = 0.5;
// Character variables can't store a string!
some_char_var = "uh oh I don't belong here!";

Additionally, variables can only be assigned to after they’ve been declared.

Good

int some_var;
some_var = 10;

Bad

some_var = 10;
int some_var;

Tasks 🎯

Reassign an even value to some_number to make the code below print out a valid statement.

#include <stdio.h>

int main() {
    int some_number;
    some_number = 11;

    // Add a new assignment here


    // No need to touch this! This prints out the variable.
    printf("%d is even!", some_number);
}

Solution ✅

#include <stdio.h>

int main() {
    int some_number;
    some_number = 11;

    // Add a new assignment here
    some_number = 4;

    // No need to touch this! This prints out the variable.
    printf("%d is even!", some_number);
}
