After successfully executing the 'hello.c' program, I'm unable to execute 'mario.c' because terminal says 'stio.h' file not found (which IMO doesn't make any sense since 'hello.c' runs perfectly). Any ideas?

jharvard@appliance (~/Dropbox/pset1): make hello
clang -ggdb3 -O0 -std=c99 -Wall -Werror    hello.c  -lcs50 -lm -o hello
jharvard@appliance (~/Dropbox/pset1): ./hello
hello, world
jharvard@appliance (~/Dropbox/pset1): make mario
clang -ggdb3 -O0 -std=c99 -Wall -Werror    mario.c  -lcs50 -lm -o mario
**mario.c:1:10: fatal error: 'stio.h' file not found
#include <stio.h>

  • as beginner CS students (CS50s constituency), typos are very much on topic (imo). this thread did indeed help me, quite quickly. is "off-topic" deemed by stackexchange folks, or CS50 moderators? seems harsh.

Change it to

 #include <stdio.h>

You've got a typo.
