Having the same issue too, it was working just fine yesterday

[gotjon05]

For me the format string is creating the error "Uncaught TypeError: Callback must be a function. Received undefined"

This fails: #include <stdio.h> int main(){ printf("%s", please work); }

And this works: int main(){ printf("please work"); }

I found the solution- there is very silly mistake in my code i.e. I forgot to write semicolon and also mis-spell the cout (this solution is only for my error )if you have the same comment here.

Guys, i just found out the solution for this problem. At least that is what i was doing wrong, i was not saving my file as .c or .cpp for c and c++ language that is required for gpp compiler to process.

[VedanshSharma0412]

try doing this, i think it could solve your issue. this worked in my device.

/* you did not declare the string "please work", hence why your program will crush (%s is a place holder for a non declared string.). here is a sample that should work fine.*/

#include <stdio.h> #define SIZE 50 int main(void) { char string[SIZE] = "please work," ; printf("%s \n",string); }
