c – 阵列/指针混乱

#include <iostream>

using namespace std;

void PrefixSum(float * input,float * output,int n){
    float sum = 0;
    for (int i=0;i<n;i++){
        float value = input[i];
        sum += value;
        output[n] = sum;
    }    
}


int main(int argc,const char * argv[])
{
    float input[] = {1,2,3,4,5,6,7};
    float output[] = {0,0};
    PrefixSum(input,output,7);
    for (int i=0;i<7;i++){
        cout << output[i] << " ";
    }
    return 0;
