a. strl str2; b. C. if (str1 == str2) cout < < " Both strings are of the same length." < < endl; if (strlen (str1) >= strlen (str2)) strl = str2; if (strcmp (str1, str2) < 0) cout < < "strl is less that str2." < < endl; a. b. for (i = 0; i < 3; i++) for (j = 0; j < 3; j++) beta[i][j] = 0; for (i = 0; i < 3; i++) for (j = 0; j < 3; j++) beta[i][j] = i + j;
