Answer 1

#include <iostream>
using namespace std;
int main(){ 
    char c;
    int r;
    srand (time(NULL));              // initializing random number generator
    for (int i=0; i<2; i++) {    
        int caseOfChar = rand() % 2; //0 for lower case, 1 for upper case
        r = rand() % 26;             // generate a random number
        if (caseOfChar ==0)          //0: lower case
            c = 'a' + r;             // Convert to a character from a-z
        else if(caseOfChar == 1)     //1: upper case
            c = 'A' + r;             // Convert to a character from A-Z
        cout << c <<endl;
