这只是我的作业的第一部分,我已经修复了所有其他编译错误,但我不断收到此错误,theres五。试图做这个家庭作业,但我不断收到编译错误

我试过用它做所有事情,但我可能做错了什么事情。显然我是。如果你不介意的话,我可以使用一些帮助:)。顺便说一句,如果有人想知道,做simpletron。
#include <iostream>
using namespace std;
int main()
{
int memory[100]; //Making it 100, since simpletron contains a 100 word mem.
int operation; //taking the rest of these variables straight out of the book seeing as how they were italisized.
int operand;
int accum = 0; // the special register is starting at 0
int position = 0; //making the starting position to be 0.
for (int j = 0; j < 100; j++) //Simply stating that for int j is = to 0, j must be less than 100 because that is the memory limit, and for every pass-through, increment j.
memory[j] = 0;
// This is for part a, it will take in positive variables in a sent-controlled loop and compute + print their sum. These are random variables.
memory [0] = 2942;
memory [1] = 2342;
memory [2] = 3523;
memory [3] = 2031;
memory [4] = 5000;
memory [5] = 8080;
memory [6] = 3425;
j = 0; //Makes the variable j start at 0.
while (true)
{
memory[ j ]%100 = operand; // Finds the op codes from the limit on the memory (100)
memory[ j ]%100 = operation;
//using a switch loop to set up the loops for the cases
switch (operation){
case 1: //reads a variable into a word from loc.
cout <<"\n Input a positive variable: ";
cin >> memory[ operand ]; break;
case 2: // takes a word from location
cout << "\n\nThe content at location " << operand << "is " << memory[operand]; break;
case 3:// loads
accum = memory[ operand ]; break;
case 4: //stores

@pickypg请不要将作业标签添加到问题中,它目前被列入黑名单(阅读标签说明)。 – Tim
@Tim我回滚了这个变化,这是在标签的描述中没有移除,除非问题需要清理。尽管公平,但我仍然将它添加到一些新的问题。 – pickypg
@Josh:你应该努力保持缩进一致。您可能会惊讶地发现,通过正确缩进可以避免多少错误,因为您在缩进时会看到错误,例如在此处显示的错误范围中声明的变量。 :) –
