4. Write a program with two functions both called from main(). The first function just prints "Hello". In the second function ask the user to enter a number. Calculate the square root of the number and return the result to main(). In main() print the square root value.

Code:Can you help me Please? I made a logic mistake in function.Code:#include<stdio.h> #include<math.h> float fun3 (float ); main() { float answer; float a; answer = fun3(a); puts("\nBack in main"); printf("\nThe result is %.2f", answer); getch(); } float fun3 (float c) { float x; float y; printf("\nHello"); printf("\n\nPlease enter a number: "); scanf("%f",&x); y = sqrt(x); return (y); }
