Q.3 Write a c++ program that asks the user to enter two numbers (from 100 to 999) to create a matrix that have the size [a][5]. Then, the program will reverse the digits of each element in that matrix and it will print it again. As shown in figures below Enter start number of elements to make your array shoud be(from 100 to 999): 100 Enter the end number of elements to make your array, should be greater than the first number : 115 100 101 102 103 104 106 111 105 107 108 109 110 112 113 114 The matrix after reversing the digits of each element will be : 1 101 201 301 401 501 601 701 801 901 11 111 211 311 411 Process exited after 4.309 seconds with return value e Press any key to continue . Enter start number of elements to make your array shoud be(from 100 to 999): 120 Enter the end number of elements to make your array, should be greater than the first number : 170 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 The matrix after reversing the digits of each element will be : 21 121 221 321 421 521 621 721 821 921 31 131 231 331 431 531 631 731 831 931 41 141 241 341 441 541 641 741 841 941 51 151 251 351 451 551 651 751 851 951 61 161 261 361 461 561 661 761 861 961 Process exited after 7.571 seconds with return value e Press any key to continue

I'm perplexed by the idea of two-factor authentication. To what degree does it contribute to password security?

How can we tell if one method of authentication is safer than another?

Encrypt the message DEFEND using the RSA system with n = 43*59 and e = 13.  First translate each letter into an integer and group together pairs of integers, so you have three 4-digit numbers (padding 0’s in the front if necessary).  Work with each of these numbers to encrypt them.  The ciphertext should also be three 4-digit numbers.

I'm having trouble getting this book's entry code. Is there any way you could help me find it or tell me how to look for it on my Yuzu account?
