Printf() func. In main C

Question

I am trying to encrypt a message and calculate it from a seperate function with pointers to the message in the main(). Having declared an output array in main for the message to store and call within side the function and return a void function with the encrypted calculation. However instead of printing the message inside the function, how can I print the encrypted message inside the main after the function has been called?

Answer 1

ah ok make sense , so if I undertand it correctly, say if the user inputs a plain text, only the inputed text is passed as a pointer to the function to encrypt the message, then the second pointer stores the encrypted in the char array which then main() can print the encrypted message?

ah ok great! Thanks so much for your help!
