C - Variables, if, else, while

In this project, I learned about using arithmetic, logical, relational, and boolean operators in C. Additionally, I practiced declaring and defining variables of type char, int, and unsigned int, using if and if...else statements, and implementing while loops.

Tasks 📃

• 0. Positive anything is better than negative nothing

  • 0-positive_or_negative.c: C program that prints whether a randomly generated number is positive or negative, followed by a new line:
    • Completion of this source code.
    • Stores a different random number every time the program is run.
    • Prints the number followed by is positive if the number is greater than 0, is zero if the number is zero, or is negative if the number is less than 0.

• 1. The last digit

  • 1-last_digit.c: C program that prints the last digit of a randomly generated number, followed by a new line:
    • Completion of this source code.
    • Stores a different value every time the program is run.
    • Prints the string Last digit of [number] is [last_digit] and is followed by greater than 5 if the digit is greater than 5, 0 if the digit is 0, or less than 6 and not 0 if the digit is less than 6 and not 0.

• 2. I sometimes suffer from insomnia. And when I can't fall asleep, I play what I call the alphabet game

  • 2-print_alphabet.c: C program that prints the alphabet in lowercase, followed by a new line, using only the putchar function exactly twice.

• 5. Numbers

  • 5-print_numbers.c: C program that prints all single digit numbers of base 10 starting from 0, followed by a new line.

• 6. Numberz

  • 6-print_numberz.c: C program that prints all single digit numbers of base 10 starting from 0, followed by a new line, using only the putchar function exactly twice without any variables of type char.

• 7. Smile in the mirror

• 9. Patience, persistence and perspiration make an unbeatable combination for success

  • 9-print_comb.c: C program that prints all possible combinations of single-digit numbers, using only the putchar function exactly four times without any variables of type char:
    • Numbers are separated by ,, followed by a space.
    • Numbers are printed in ascending order.

• 10. 00...99

  • 10-print_comb2.c: C program that prints the numbers from 00 to 99 using only the putchar function exactly five times without any variables of type char:
    • Numbers are separated by ,, followed by a space.
    • Numbers are printed in ascending order, with two digits.

• 11. Inventing is a combination of brains and materials. The more brains you use, the less material you need

  • 100-print_comb3.c: C program that prints all possible different combinations of two digits using only the putchar function exactly five times without any variables of type char:
    • Numbers are separated by ,, followed by a space.
    • The two digits are different.
    • 01 and 10 are considered the same combination of the two digits 0 and 1.
    • Prints only the smallest combination of two digits.
    • Numbers are printed in ascending order.

• 12. The success combination in business is: Do what you do better... and: do more of what you do...

  • 101-print_comb4.c: C program that prints all possible different combinations of three digits using only the putchar function exactly six times without any variables of type char:
    • Numbers are separated by ,, followed by a space.
    • The three digits are different.
    • 012, 120, 102, 021, 201 and 210 are considered the same combination of the three digits 0, 1 and 2.
    • Prints only the smallest combination of three digits.
    • Numbers are printed in ascending order.

• 13. Software is eating the World

  • 102-print_comb5.c: C program that prints all possible combinations of two-digit numbers using only the putchar function exactly eight times without any variables of type char:
    • Numbers range from 0 to 99.
    • Two numbers are separated by a space.
    • Numbers are printed with two digits [ie. 1 is printed as 01].
    • 00 01 and 01 00 are considered the same as the combination of of the numbers 0 and 1.
    • Combinations of numbers are separated by ,, followed by a space.
    • Combinations of numbers are printed in ascending order.
