  #include <stdio.h>    void PrintFace(char eym) {     char n = '>';       printf("  %c   %c ", eym, eym);     printf("    %c ", n);            printf("  %c%c%c%c%c ", eym, eym, eym, eym, eym);        return;  }    int main() {     char usrKey = '-';         printf("Enter key: ");     scanf("%c", &usrKey);     PrintFace(usrKey);       return 0;  }  

Explanation / Answer

#include //include the header file void PrintFace(char eym) //function declared which accepts a char variable (passed by value) and doesn't return any value to the caller function. { char n = '>'; //function variable that stores a char value printf(" %c %c ", eym, eym); // to print the value of char variable eym twice printf(" %c ", n); // to print the value of char variable n once printf(" %c%c%c%c%c ", eym, eym, eym, eym, eym); // to print the value of char variable eym 5 times return; // returns void to the caller function indicating normal execution } int main() //main function to execute all the functions { char usrKey = '-'; // function variable that stores char value.initialised with '-' printf("Enter key: "); // to print the message on the console scanf("%c", &usrKey); //to take the input from user and store it in the variale userkey. PrintFace(usrKey); //calling the function PrintFace and passing it the value of userkey variable entered by the user. return 0; //return statement to return 0 if execution is normal }
