To write the C Program, Open the C Console and write the following code :

#include<studio.h>

int main() {
    printf("Hello world");
    return 0;
}

Here, #include<stdio.h> means you are including functions from in-built library, stdio.h. stdio.h contains standard input and output functions like printf() and scanf().

Then you are creating a function named as main(), indicating you are returning integer value with int main(). Compiler will look for the function main and execute that function in the program. So your program must have this main function.

printf() function print data in the console.

return 0 means you returned the integer value 0 to the main function. Generally, 0 can be indicated as successful execution and 1 as failed execution.
