    How do i read a file in from a vector?

    So my program works all right, but I can't read my information from a file into my vector, what am I doing wrong?

    Code:
    vector<char> grades;
	grades.push_back ('A');
	grades.push_back ('B');
	grades.push_back ('C');
	grades.push_back ('D');
	grades.push_back ('E');
    
	

	// declare a place to hold scores read from a file 
	//int scores[10]={0};
	vector<int>
    ...

      srand()

      So I've fixed pretty much all of my problems for my program which is supposed to seed the random number generator for rolling two dice. My program compiles, but I cannot get the random numbers to happen, and I've tried several different things. I've included all of my code, but really the only thing I can't get to work right is the random number generator, so any help would be great.

      Code:
      #include <iostream>
#include <string>
      ...

        Vectors in C++

        I have an assignment where the program was written for me and we had to change all of the arrays to vectors. When I got the assignment back I didn't pass it off because I needed to populate a particular vector by using the push_back function, but I can't figure it out, so I'm going to post my whole program, but I think this is the only part I need help with.

        Code:
        #include <iostream>
#include <fstream>
#include
        ...

          Vectors in C++

          So I have this program where I'm supposed to change all arrays into vectors. The program takes test values and assigns grades for them. The only problem is i've tried to change them into vectors, but I'm coming up with all sorts of errors, so here is some code with the array and the vector part is what I've tried to do.

          Code:
          char grades[] = {'A', 'B', 'C', 'D', 'E'};
	vector<char> grades; //['A', 'B', 'C', 'D', 'E'];
          ...

              '=': function as left operand

              I've made some corrections to the code I posted earlier, and thanks to those that responded because I have no idea what I'm doing. But now my code comes up with an error I don't understand. Here is my code that I'm having problems with:

              Code:
              bool isLeap (int year)	
{
	return ((isLeap = (year) / 4) || ((isLeap = (year) / 100) && ( isLeap = (year) / 400)));
              ...

                '=': function as left operand

                Hey I'm really new to programming and I can't figure out what I'm doing wrong. So I was asked to write a program that determines whether a year is a leap year or not. So I wrote the following formula in a .h file:

                bool isLeap (int)
                {
                return ((isLeap = (year) / 4) || ((isLeap = (year) / 100) && ( isLeap = (year) / 400)))

                }

                it always brings up errors that I don't understand, so if...
