Step 1: Requirements You are developing a software package that requires users to enter their own passwords. Loop until the passwords meet the software criteria: · The password should be at least 6 characters long · The password should contain at least one uppercase and one lowercase letter · The password should have at least one digit The program should have an isValid function that will test if the password is valid. Use the following code to declare a password variable with a global constant int SIZE=80; char password[SIZE]; Next use a while(true) to continue looping until the user enters a valid password. Read in the password and call the isValid program. You can use the isupper(), islower(), and isdigit() functions. For example: if (isdigit(*password)) //if this is true, you know the password has at least one digit. Output from Program: Password requirements: - The password should be at least 6 characters long - The password should contain…
