Change order of how input is collected

[haidernumero]

supposed, user should enter 5 number first and then they will select whether to find the smallest number, largest, sum and average. but then. my program here, do the selection first then enter five number. can anyone help me how to repair it. coz i'm blurred.

#include <stdio.h>
 
int menu(void);        //list of function listed in this program
void smallestNo(void);
void largestNo(void);
void sum(void);
void average(void);
 
 
int main()
{
  int selection;
 
  selection=menu();
 
  switch(selection)
  {
     case 1:smallestNo();
              break;
     case 2:largestNo();
              break;
     case 3:sum();
              break;
     case 4:average();
              break;
     case 5:printf("EXIT....");
              break;
     default:printf("\nYou have entered INVALID selection!\nPlease try again!");
 
  }//end switch
 
  return 0;
}//end main
 
 
int menu(void)

Exactly what are you trying to fix?

[donbock]

weaknessforcats:
The posted program first has the user specify the type of operation they wish to perform; and then has them enter the numbers to be acted on. Sounds like the OP is asking for help changing the program to make those requests in the opposite order.

haidernumero:
Where did you obtain the program that you posted?

weaknessforcats:
thing is i want user to enter their 5 number first and then ask them to choose to find smallest,largest sum or average. program i wrote up there actually ask the user to select between smallest, largest etc. first then ask them to enter the number.

donbock:
that i do by myself. why?
