code :

#include <stdio.h>
int main(){
int i;
scanf("%d", &i);
printf("You entered: %d\n", i);
return 0;
}

Terminal:

PS C:\Users*\OneDrive\Documents\INTERVIEW PREP\DSA and Small Learnings> & 'c:\Users**.vscode\extensions\ms-vscode.cpptools-1.23.0-win32-x64\debugAdapters\bin\WindowsDebugLauncher.exe' '--stdin=Microsoft-MIEngine-In-caznmueg.sx2' '--stdout=Microsoft-MIEngine-Out-kpfaclzx.m3o' '--stderr=Microsoft-MIEngine-Error-nq1rgwan.vxy' '--pid=Microsoft-MIEngine-Pid-d12jsuyv.lf0' '--dbgExe=C:\MinGW\bin\gdb.exe' '--interpreter=mi'

When I press F5, means i debug my C code, it not prints anything or neither take any inputs if scanf is there, if debugger is at scanf , and if i press F10 , then as shown in picture, Nothing happens. I can Only hover and see the variable value. I have installed


 set up,

 ```codeLLB```

 and code runner extensions, as well.

Also, If I not put debugger at scanf function: it waits for input ,but when i write something and hit enter, nothing happens, also the debugger not allow to step next step...And after that if i stop the debugger, then what ever i wrote in terminal ,shows there immediately. Example: if i wrote fffff and then stop debugger then that word executes in terminal!
