char email[30];

// COPY name TO email

//Concatenate email with '.'

//Concatenate badge with email

//Concatenate @ with email

//Concatenate company name with email

// Add a domain by concatenating .edu with email

// Search for the last occurrence of .

//The method returns a pointer pointing to the beginning of .edu

// Change the values next of the pointer to make '.edu' all uppercase

// Subtract -32 from the letters and that will make it uppercase

// answer will be .EDU

// Use strcmp to compare the previous pointer to ".EDU"

// Print the email using printf, the specifier is %s

//an outcome will look like : [email protected]

p points to .EDU
