Hi there, I coded this program in C language and it works perfectly. I am wanting to use functions so that the main is pretty much empty. I got stuck and I am completely unable to make the functions work. I wish to make two more functions in my program. One that prints the instructions and scans the data from the user, and lastly one that prints the output. I did make a function that works already which manipulates the data to order it correctly. I have put in my code where I want the functions to begin:

Here is my code:

#include

#include

#include

//prototype for the function that sorts names and ages

void sortInputData(char name[20][100], int age[20], int n, char lastName[20][100]);

int main()

{

char name[20][100];

char lastName[20][100];

int age[20];

int numberEntries = 0;

int c = 0;

//***************Function to Print Instructions *****************//

//print initial instructions to user

printf("Please enter the number of people you wish to enter into the database: ");

//scan how many entries user wishes - store in numberEntries

scanf("%d", &numberEntries);

//loop for how ever many entries user decided on

for (int i = 0; i < numberEntries; i++)

{

//clears out the input buffer each loop

while ((c = getchar()) != ' ')

{

}

//print instructions to user

printf(" For person #%d: ", i + 1);

printf("Enter name: ");

scanf("%s",name[i]);

printf("Enter last name: ");

scanf("%s",lastName[i]);

printf("Enter age: ");

scanf("%d", &age[i]);

}

//***************Function to Print Instructions *****************//

// call the sortNamesAndAges() function

sortInputData(name, age, numberEntries, lastName);

//*******************Function to print Output****************//

printf(" --------------- Printing sorted names --------------- ");

for (int i = 0; i < numberEntries; i++)

{

// print the user names and ages

printf("name: %s ", name[i]);

printf("last name: %s ", lastName[i]);

printf("age: %d ", age[i]);

//*******************Function to print Output****************//

}

return 0;

}

void sortInputData(char name[20][100], int age[20], int n, char lastName[20][100])

{

// temporary char array 's' and int 'temp' to use for copying

char s[100];

char a[100];

int temp;

for (int i = 0; i < n; i++)

{

for (int j = i + 1; j < n; j++)

{

if (strcmp(name[i], name[j]) > 0)

{

// swap names

strcpy(s, name[i]);

strcpy(name[i], name[j]);

strcpy(name[j], s);

//swap the order of the age

temp = age[i];

age[i] = age[j];

age[j] = temp;

strcpy(a, lastName[i]);

strcpy(lastName[i], lastName[j]);

strcpy(lastName[j], a);

}

}

}

}

I will for sure thumbs up any help on this topic!!! Thank you so much
