Write a C program that prints exactly and that piece of art is useful" - Dora Korpar, 2015-10-19, followed by a new line, to the standard error.You are not allowed to use any functions listed in the NAME section of the man (3) printf or man (3) putsYour program should return 1Your program should compile without any warnings when using the -Wall gcc option
Solution 1
Here is a simple C program that meets your requirements:
#include <unistd.h>
int main(void) {
write(2, "and that piece of art is useful\" - Dora Korpar, 2015-10-19\n", 59);
return (1);
}
Here's how it works:
-
#include <unistd.h>: This line includes the header file unistd.h which contains the declaration of the write function. -
int main(void): This is the main function where the program starts execution. -
write(2, "and that piece of art is useful\" - Dora Korpar, 2015-10-19\n", 59);: The write function is used to write data to a file descriptor. The first argument is the file descriptor, where 2 represents the standard error. The second argument is the string to be printed. The third argument is the number of bytes to be written, which is the length of the string including the null character. -
return (1);: This line returns 1 from the main function, indicating that the program has executed successfully. -
The program does not use any functions listed in the NAME section of the man (3) printf or man (3) puts, and it should compile without any warnings when using the -Wall gcc option.
Solution 2
Sure, here is a simple C program that meets your requirements:
#include <unistd.h>
int main(void) {
write(2, "and that piece of art is useful\" - Dora Korpar, 2015-10-19\n", 59);
return (1);
}
Here's a step-by-step explanation of the code:
-
#include <unistd.h>: This line includes the unistd.h header file. This header file is necessary for using the write function. -
int main(void): This line defines the main function. The main function is the entry point of the program. -
write(2, "and that piece of art is useful\" - Dora Korpar, 2015-10-19\n", 59);: This line uses the write function to print the required string to the standard error. The first argument of the write function is the file descriptor. Here, 2 is the file descriptor for standard error. The second argument is the string to be printed. The third argument is the number of bytes to be written. Here, 59 is the length of the string including the newline character. -
return (1);: This line returns 1 from the main function. As per the requirement, the program should return 1. -
The program does not use any functions listed in the NAME section of the man (3) printf or man (3) puts. It only uses the write function, which is not listed in these sections.
-
The program should compile without any warnings when using the -Wall gcc option. The -Wall option in gcc enables all compiler's warning messages. This option is useful for catching potential issues in the code.
