我有一个模板类linear search TEMPLATE.h，它是一个通用数组和一个模板函数arrayTemplate.h，它被声明为类getArraySize()的朋友，所以它可以使用类的成员函数a和类的数据成员 #ifndef arrayTemplate
#define arrayTemplate
#include"linear search TEMPLATE.h"
#include<iostream>
using namespace std;
template <class T>
class array_T {
private:
T *a;
int arraySize;
public :
friend void linearSearch(array_T object);
array_T(int s) {
arraySize = s;
a = new T[arraySize];
for (int i= 0; i < arraySize; ++i) {
a[i] = 0;
}
}
~array_T() {
delete[]a;
}
void setArray() {
for (int i=0; i < arraySize; ++i) {
cout << "Enter the elements of the array " << endl;
cin >> a[i];
}
}
void getArray() {
for (int i=0; i < arraySize; ++i) {
cout << a[i] << endl;
}
}
int getArraySize() {
return arraySize;
}
};
#endif
这是一个动态分配数组
arrayTemplate.h
#include"arrayTemplate.h"
#include<iostream>
using namespace std;
template <class T>
//void linearSearch(T desiredData, int arraySize, T *elemnts) {
void linearSearch(array_T<T> object , T desiredData) {
int arraySize = object.getArraySize();
int loc = -1;
int i = 0;
for (i = 0; i < arraySize; ++i) {
if (object.a[i] == desiredData) {
loc = i;
break;
}
}
if (loc > 0) {
cout << "the Item is found at position " << i + 1 << endl;
}
else {
cout << "the item is not found ";
}
}
线性搜索TEMPLATE.h
#include"arrayTemplate.h"
#include"linear search TEMPLATE.h"
#include<iostream>
using namespace std;
int main() {
array_T<int> myArray(7);
myArray.setArray();
linearSearch(myArray,50)
return 0 ;
}
的main.cpp
from collections import defaultdict
def saving_multiple_scores():
with open(class_number, 'r') as f: # don't use file
data = defaultdict(list)
for line in f:
line = line.strip()
if not line:
continue # skip over any blank lines in the file
key, value = line.split(':')
data[key.strip()].append(value.strip())
# file.write removed because we don't write in readmode
with open(class_number, 'a') as f:
# using 'a' mode will append the score lists
# to the end of the file
# to overwrite the file completely, use 'w'
for key, value in data.items():
line = '%s:%s\n' % (key, ','.join(value),)
f.write(line)
print '%s' % line,
这些是我得到的错误
