To clarify before next exam

• Conversions between char and int.
• Declaration and assignation of character strings and integer arrays on separate lines.
• Global, static, constant (???).

The Norm says

• Each C keyword must be followed by a space, except for keywords for types (such as int, char, float, etc.), as well as sizeof.
• Declaration and an initialisation cannot be on the same line, except for global variables (when allowed), static variables, and constants.
• Multiple assignments are strictly forbidden.
• You may add a new line after an instruction or control structure, but you’ll have to add an indentation with brackets or assignment operator. Operators must be at the beginning of a line.
• Control structures (if, while..) must have braces, unless they contain a single line or a single condition.
• A function can take 4 named parameters maximum.
• You can’t declare more than 5 variables per function.
• You cannot include a .c file.
• You cannot have more than 5 function-definitions in a .c file.

Characters

int		i;
char	c;

char = i + '0';
char = (char) i; // ???

---

Integers

char	c;
int		i;

int = c - '0';
int = (int) c; // ???

---

Pointers

---

Character Arrays a.k.a. Strings

array[index] == *(array + index)

array[0] == *(array + 0) == *array		// ????
array[1] == *(array + 1)

char  array[3];

array[0] = 'a';
array[1] = 'b';
array[2] = 'c';

// Unfortunately, this is not allowed by the Norm.
char  array[] = "Abc";

---

Integer Arrays

array[index] == *(array + index)

array[0] == *(array + 0) == *array		// ????
array[1] == *(array + 1)

int array[3];

array[0] = 1;
array[1] = 2;
array[2] = 3;

// Unfortunately, this is not allowed by the Norm.
int array[] = {1, 2, 3};

Recursion

str[index] = str[index - 1] + str[index];

Main Arguments

int main(int argc, char **argv);
