Solved: sleep in c programming

C Programming is a versatile tool in the realm of development. It provides robust solutions to complex problems and has a rich library that supports a range of functionalities. One such topic to consider is managing sleep operation in C programming. It may sound like a simple task, but it involves deep understanding of libraries and their functions. Let’s dive in to comprehend this fascinating feature of C.

Role of sleep in C Programming

Sleep function in C Programming plays a fundamental role in controlling the sequence of processes. It’s utilized to put a program on hold for a specified number of seconds. In real-world scenarios, it provides beneficial results when a task needs to be delayed for a certain interval. In C language, sleep operation is supported by time.h library, through its function sleep().

The usage of sleep function can vary based on the problem at hand. Let’s dive deeper into its functionality by exploring a sample problem and its resolution.

The Problem Scenario

Consider a situation where we need to print the Fibonacci series, with a time delay of one second between each output. This delay can be efficiently managed using the sleep function.

Now let’s see the solution to this problem and then understand the code in steps.

[h2> The Solution

Here’s the solution to the problem using sleep function in C programming.


int main()
int a = 0, b = 1, next, n;

printf(“Enter num of termsn”);
scanf(“%d”, &n);

for ( int i = 1 ; i <= n ; i++ ) { if ( i <= 1 ) next = i; else { next = a + b; a = b; b = next; } printf("%dn",next); sleep(1); } return 0; } [/code]

Code Explanation

  • The code begins with the inclusion of standard input/output library using #include, which is required for input and output operations.
  • The time.h library is included for using sleep function in the code.
  • In the main function, we declared necessary variables a, b, and next for Fibonacci series and a variable n to obtain user input for the number of terms.
  • The scanf function is used to take the user input which will define the limits of Fibonacci series.
  • A for loop is then used which will execute till the nth term defined by the user. The if block inside the loop calculates and prints the Fibonacci sequence.
  • The sleep function is called after each output, causing a delay of 1 second before the next iteration begins.

Working with sleep function can vastly expand the range of problems we can solve with C programming. While offering beneficial outcomes, it also deeps our understanding of libraries and their vast functionalities.
