0x01-variables_if_else_while

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

All Tasks Here

• 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.
    • The variable n will store a different value every time you will run this program.
    • The output of the program should be:
      • The number, followed by
        • if the number is greater than 0: is positive
        • if the number is 0: is zero
        • if the number is less than 0: is negative
      • followed by a new line.

• 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:
    • Compilation of this source code.
    • The variable n will store a different value every time you run this program.
    • The output of the program should be:
      • The string Last digit of, followed by
      • n, followed by
      • the string is, followed by
        • if the last digit of n is greater than 5: the string and is greater than 5.
        • if the last digit of n is 0: the string and is zero
        • if the last digit of n is less than 6 and not 0: the string and is less than 6 and not 0
      • followed by a new line

• 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.

• 3. When I was having that alphabet soup, I never thought that it would pay off

  • 3-print_alphabets.c :C program that prints the alphabet in lowercase, then in uppercase, followed by a new line, using only the putchar function exactly three times.

• 4. alphABET

  • 4-print_alphabt.c :C program that prints the alphabet in lowercase except for the letters q and e, 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

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

• 8. Hexadecimal

  • 8-print_base16.c :C program that prints all the numbers of base 16 in lowercase, followed by a new line, using only the putchar function exactly three times.

• 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 must be separated by ,, followed by a space
    • Numbers should be printed in ascending order
    • You can only use the putchar function (every other function (printf, puts, etc…) is forbidden)
    • All your code should be in the main function
    • You can only use putchar four times maximum in your code
    • You are not allowed to use any variable of type char

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

  • 10-print_comb2.c: Write a program that prints all possible different combinations of two digits.
    • Numbers must be separated by ,, followed by a space
    • The two digits must be different
    • 01 and 10 are considered the same combination of the two digits 0 and 1
    • Print only the smallest combination of two digits
    • Numbers should be printed in ascending order, with two digits
    • You can only use the putchar function (every other function (printf, puts, etc…) is forbidden)
    • You can only use putchar five times maximum in your code
    • You are not allowed to use any variable of type char
    • All your code should be in the main function

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

  • 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 must be separated by ,, followed by a space
    • The three digits must be different
    • 012, 120, 102, 021, 201, 210 are considered the same combination of the three digits 0, 1 and 2
    • Print only the smallest combination of three digits
    • Numbers should be printed in ascending order, with three digits
    • you can only use the putchar function (every other function (printf, puts, etc…) is forbidden)
    • You can only use putchar six times maximum in your code
    • You are not allowed to use any variable of type char
    • All your code should be in the main function
