Hi I am on pset1 and I seem to be missing studio.h. Could you tell me how to install studio.h?

Here is my program:

  #include <studio.h>
int main(void)
    printf("hello world!\n");

Here is the error that I received:

 ~/workspace/pset1/ $ make hello
clang -fsanitize=integer -fsanitize=undefined -ggdb3 -O0 -std=c11 -Wall -Werror -Wextra -Wno-sign-compare -Wshadow    hello.c  -lcrypt -lcs50 -lm -o hello
hello.c:1:10: fatal error: 'studio.h' file not found
  • stdio stands for "standard input / output" (or similar), provides functions for accessing files, console in/out/err are like special files
