In this example, we will show you how to create a thread in C programming.

Create Thread in C with Example

In this example, we will be creating a thread to perform a task. In this task, we will display the sequence numbers from 1 to 5. The focus of this recipe is to learn how a thread is created and how the main thread is asked to wait until the thread finishes its task.

Let's create a file named createthread.c and add the following source code to it:

#include <stdio.h> #include <stdlib.h> #include <pthread.h> void *runThread(void *arg) {	int i;	printf("Running Thread \n");	for(i=1;i<=5;i++) printf("%d\n",i);	return NULL; } int main() {	pthread_t tid;	printf("In main function\n");	pthread_create(&tid, NULL, runThread, NULL);	pthread_join(tid, NULL);	printf("Thread over\n");	return 0; } 

To compile and run the above C program, you can use C Programs Compiler Online tool.

Output:

In main function Running Thread 1 2 3 4 5 Thread over
