G c 24-hour time (also known in the U. S. as military time) is widely used around the world. Time is expressed as hours since midnight. The day starts at 00:00, and ends at 23:59. Write a program that converts am/pm time to 24-hour time. The input is two numbers and a string. If the input is 2 30 pm, the output should be 14:30. If the input is 12 01 am, the output should be 00:01. Hints: Think of how each hour should be handled. 12 00 am -12 59 am becomes what

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;
