A. Write a function called shortestString, which takes an array of string with the array capacity and returns the index of the shortest string in the array.

B.Write a function called triangle that takes the size of the triangle as its parameter, prints a triangle with alphabets A-Z, after Z go back to A Test with the following 2 main functions int main(){ string x[4] = {"This", "is", "one", "example"}; int index_of_shortest = shortestString(x, 4); cout << x[index_of_shortest] << endl; //prints:is triangle(5); /*The above function prints following: A BC DEF GHIJ KLMNO */ return 0; } int main(){ string array[6] = {"This ", "is", " another", " ", "one", "!!!"}; int index_of_shortest = shortestString(x, 6); cout << x[index_of_shortest] << endl; //prints: triangle(7); /*The above function prints following: A BC DEF GHIJ KLMNO PQRSTU VWXYZAB */ return 0; }

C. Explain the output of the following program as comments in the program.

int main(int argc, char* argv[]) { int i = 0; cout << i - 1 << endl; //i is 0, 0 - 1 evaluates to -1, print out this value, variable i hasn't changed. cout << i-- << endl; // cout << argc << i << endl; // i = 0; string st = argv[++i + 1]; // st += "CI"; // cout << argv[i] << endl; // // i is 1, argv[1] is the second word of this program's argument given at the time when running this program, in this case, QC cout << argv[i][i] << endl; // cout << st << endl; // cout << st[i++] << endl; // cout << i << endl; // cout << st[i]++ << endl; // cout << st << endl; // cout << st.substr(0,2) << endl; // st.insert(st.size() - 2, " "); // cout << st.substr(st.size()-3) << endl; // while (i++ < 10) {} // cout << i << endl; // return 0; } To run this program, ./a.out QC CS
