Answer 1

#include <iostream>//for cin, cout 
#include <string>//For string


using namespace std;
//prototype of functions
string swapLetters(string name);
void displayNames(string studentNames[25]);


//The start point of the program
int main() { 
	//a string array to store the name of 25 students
	string studentNames[25];
	//get 25 names from the user
	for(int i=0;i<25;i++){
		cout << "Enter name "<<(i+1)<<": ";
		getline(cin,studentNames[i]);
	}
	//display the names before swapping
	cout<<endl << "The names before swapping: "<<endl;
	//display names
	displayNames(studentNames);
	//swap letters
	for(int i=0;i<25;i++){
		studentNames[i]=swapLetters(studentNames[i]);
	}
	//display the names after swapping
	cout<<endl << "The names after swapping: "<<endl;
	//display names
	displayNames(studentNames);
    
	//Delay
    system("pause");
    return 0; 
}
//This function allows to swap the first letter of the name to last letter 
string swapLetters(string name){
	char tmp=name[name.length()-1];//get the last letter 
	name[name.length()-1]=name[0];//swap the letters
	name[0]=tmp;//set the last letter as the first letter
	return name;//return new name
}
//This function allows to display names
void displayNames(string studentNames[25]){
	for(int i=0;i<25;i++){
		cout <<(i+1)<<". "<< studentNames[i]<<endl;
	}
}
