1-alphabet.c -Write a function that prints the alphabet, in lowercase, followed by a new line.

Prototype: void print_alphabet(void); You can only use _putchar twice in your code

2-print_alphabet_x10.c -Write a function that prints 10 times the alphabet, in lowercase, followed by a new line.

Prototype: void print_alphabet_x10(void); You can only use _putchar twice in your code

3-islower.c -Write a function that checks for lowercase character.

Prototype: int _islower(int c); Returns 1 if c is lowercase Returns 0 otherwise FYI: The standard library provides a similar function: islower. Run man islower to learn more.

4-isalpha.c -Write a function that checks for alphabetic character.

Prototype: int _isalpha(int c); Returns 1 if c is a letter, lowercase or uppercase Returns 0 otherwise FYI: The standard library provides a similar function: isalpha. Run man isalpha to learn more.

5-sign.c -Write a function that prints the sign of a number.

Prototype: int print_sign(int n); Returns 1 and prints + if n is greater than zero Returns 0 and prints 0 if n is zero Returns -1 and prints - if n is less than zero

6-abs.c -Write a function that computes the absolute value of an integer.

Prototype: int _abs(int); FYI: The standard library provides a similar function: abs. Run man abs to learn more.

7-print_last_digit.c -Write a function that prints the last digit of a number.

Prototype: int print_last_digit(int); Returns the value of the last digit

8-24_hours.c -Write a function that prints every minute of the day of Jack Bauer, starting from 00:00 to 23:59.

Prototype: void jack_bauer(void);

9-times_table.c -Write a function that prints the 9 times table, starting with 0.

Prototype: void times_table(void);

10-add.c -Write a function that adds two integers and returns the result.

Prototype: int add(int, int);

11-print_to_98.c -Write a function that prints all natural numbers from n to 98, followed by a new line.

Prototype: void print_to_98(int n); Numbers must be separated by a comma, followed by a space Numbers should be printed in order The first printed number should be the number passed to your function The last printed number should be 98 You are allowed to use the standard library 100-times_table.c -Write a function that prints the n times table, starting with 0.

Prototype: void print_times_table(int n); If n is greater than 15 or less than 0 the function should not print anything

101-natural.c -If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Write a program that computes and prints the sum of all the multiples of 3 or 5 below 1024 (excluded), followed by a new line.

You are allowed to use the standard library

102-fibonacci.c -Write a program that prints the first 50 Fibonacci numbers, starting with 1 and 2, followed by a new line.

The numbers must be separated by comma, followed by a space , You are allowed to use the standard library

103-fibonacci.c -Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89. By considering the terms in the Fibonacci sequence whose values do not exceed 4,000,000, write a program that finds and prints the sum of the even-valued terms, followed by a new line.

You are allowed to use the standard library

104-fibonacci.c -Write a program that finds and prints the first 98 Fibonacci numbers, starting with 1 and 2, followed by a new line.

The numbers should be separated by comma, followed by a space , You are allowed to use the standard library You are not allowed to use any other library (You can’t use GMP etc…) You are not allowed to use long long, malloc, pointers, arrays/tables, or structures You are not allowed to hard code any Fibonacci number (except for 1 and 2)
