C Programing

C programming language is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning C Programming:

Easy to learn

Structured language

It produces efficient programs

It can handle low-level activities

It can be compiled on a variety of computer platforms

//Introducing Guess My Number (GAME)

// Guess My Number
// The classic number guessing game




int main()
{
int secretNumber = rand() % 100 + 1; // random number between 1 and 100
int tries = 0;
int guess;

printf("\tWelcome to Guess My Number\n\n");

do
{
printf("Enter a guess: ");
scanf("%d", &guess);
++tries;

if (guess > secretNumber)
{
printf("Too high!\n\n");
}
else if (guess < secretNumber)
{
printf("Too low!\n\n");
}
else
{
printf("\nThat's it! You got it in %d guesses!\n", tries);
}

} while (guess != secretNumber);

return 0;
}

main() {
int i, j, num=1;
for (i=1; i

ArmStrong




main()
{
int number, n, num, check=0, remainder, digit=0;
printf(" \n Enter the number for check ArmStrong :: ");
scanf("%d",&number);
num = number;
n = number; // for last checking the number
while (num > 0) {
remainder = num % 10;
num = num / 10;
digit++;
}
printf("%d", digit);
while (number > 0) {
remainder = number % 10;
check = check + (float)pow(remainder, digit);
number = number / 10;
}
if (check == n) {
printf(" \n %d is ArmStrong number.", check);
} else {
printf("\n Its Not.");
}
getch();
}

In a C program, all lines that start with # are processed by preprocessor which is a special program invoked by the compiler. In a very basic term, preprocessor takes a C program and produces another C program without any #
