Snippets

• Including bash scrips

#include <cstdlib>  // For the system function

int main() {
	// Replace "your_script.sh" with the actual path to your bash script
	const char* scriptPath = "your_script.sh";

	// Run the bash script using the system function
	int result = system(scriptPath);

	// Check the result of the system call
	if (result == 0) {
		// The script was executed successfully
		// Add your FLTK code or other logic here
	} else {
		// There was an error executing the script
		// Handle the error or display a message
	}

	return 0;
}

• Replacing first set of characters with a particular character(memset) Description : The C library function void *memset(void *str, int c, size_t n) copies the character c (an unsigned char) to the first n characters of the string pointed to, by the argument str. Application : Can be used to set all array to 0

// Program to replace first 7 bytes with $ symbol
#include <stdio.h>
#include <string.h>

int main () {
   char str[50];

   strcpy(str,"This is string.h library function");
   puts(str);

   memset(str,'$',7);
   puts(str);
   
   return(0);
}

Output

This is string.h library function
$$$$$$$ string.h library function
