Given a first string on one line and a second string on a second line, append the second string to the first string and then the result. Ex: If the input is:

Read a 2-character string from input into variable inputString. Declare a Boolean variable isValid and assign isValid with true if inputString contains a lowercase letter. Otherwise, assign isValid with false. Ex: If the input is y-, then isValid is assigned with true, so the output is: Valid string Ex: If the input is 21, then isValid is assigned with false, so the output is: Invalid string Note: Use getline(cin, inputString) to read the entire line from input into inputString. #include <iostream>#include <string>#include <cctype>using namespace std; int main() { string inputString; /* Your code goes here */ if (isValid) { cout << "Valid string" << endl; } else { cout << "Invalid string" << endl; } return 0;}

1. Write a program that reads a number between 1,000 and 999,999 from the user, where the user enters a comma in the input. Then print the number without a comma. Here is a sample dialog; the user input is in color: Please enter an integer between 1,000 and 999,999: 23,456 23456 Hint: Read the input as a string. Measure the length of the string. Suppose it contains n characters. Then extract substrings consisting of the first n - 4 characters and the last three characters.

Read string integer value pairs from input until "Done" is read. For each string read: • If the following integer read is less than 40, output the string followed by ": low on stock". • Otherwise, output the string followed by ": well stocked". End each output with a newline. Ex: If the input is Oven 43 Curtain 7 Pillow 1 Done, then the output is: Oven: well stocked Curtain: low on stock Pillow: low on stock 1 #include 2 #include 3 using namespace std; 4 5 int main() { 6 7 8 9 10 } * Your code goes here */ return 0;

ASuppose that x and y are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iff at least oneof the variables is False.B.Suppose that x, y, and z are variable names that already refer to Boolean values.Write an expression (not a statement!) that evaluates to True iffat least two of the three variables (x, y, z) are True.C. Consider the following function headers and type contracts:def aragorn(x: int, y: str, z: float) -> str:def gandalf(x: list) -> list:def elrond(x: list, y: bool) -> bool:If the following code runs without errors, what is a header and type contractfor treebeard?a = aragorn(11, 'good', 2.0)b = treebeard(5, gandalf([1, 2, 3]), a)print(elrond(gandalf([4, 5]), b))Write the header and type contract for treebeard.

Input an integer value. If the no. is ODD print the message "Inputted no. is ODD", otherwise print "Inputted no. is EVEN".

Select all regular expressions below that match exactly the same strings as are accepted by the FSA pictured: 0ドル a*(ba)*b a b(a*b)*b(alb)* a*b(ab)* (a*b)(aa*b)* a*(ba*)(baa*)*b

Write code to determine if the first character in an input string str is a lowercase character. If the first character is lowercase, output "issue", otherwise output "no problem". in java
