Executing .exe files using system command or "!" - passing arguments as a variable, without manually entering each time.

i have a simple code written in c(hello.cpp file) and made an executable file out of it. -- please find the attachment

now testing this hello.exe file generated, in matlab: hello.m

this gives me a result

• decryption
• messages:data
• mac_trunc_verify:encrypt_data
• message_ID:12
• counter_lv=4

but what i am expecting is: with the hello_new.m file without entering the values manually beacuse my data keeps changing

• decryption
• messages:data
• mac_trunc_verify:encrypt_data
• message_ID:12
• counter_lv=4

instead my result is

• decryption
• messages:a
• mac_trunc_verify:b
• message_ID:c
• counter_lv=d

system(sprintf('"hello.exe" %s %s %s %s', a, b, c, d));

Remember, when you have something inside of quotation marks, it is a string and variable names will not be substituted to values within it.
