Changing default terminal of Codeblocks 13.12 in Windows
Solution 1:
Almost all words from your question may be trimmed.
So, if your question was in fact "How to set up ConEmu as default terminal for CodeBlocks" you may easily find the answer in docs. Just specify proper names as hooked executables
codeblocks.exe|gdb.exe
You have problems because C:B is trying to execute the following:
C:\Program Files (x86)\CodeBlocks/cb_console_runner.exe "C:\Users\Akash\Google Drive\Codes\codeforces\H_designation.exe"
Do they know that paths with special symbols like spaces must be put in double quotes? Reinstall C:B in the folder without spaces, or run C:B using short names, sort of
C:\PROGRA~2\CodeBlocks\codeblocks.exe
