計劃在C停止無理由

Question

你好，這是我的職責，請幫助我知道是什麼問題：

#include <stdlib.h> 
#include <stdio.h> 
#include <time.h> 
#define LENGTH 10 

void searchingFunc(int arr[],int number,int specialNumber); 
void placesOfNum(int arr[],int number,int specialNumber); 
int evenPlaces(int arr[],int number,int specialNumber); 

int main() 
{ 
    int len =10,someNum =0,i=0,ans=0; 
    int someArr[LENGTH]={0}; 
    for(i=0;i<len;i++) 
    { 
     printf("enter a number: \n"); 
     scanf("%d",&someArr[i]); 
    } 
    printf("now, enter the other number\n"); 
    scanf("%d",&someNum); 
    searchingFunc(someArr,len,someNum); 
    placesOfNum(someArr,len,someNum); 
    ans = evenPlaces(someArr,len,someNum); 
    printf("%d",ans); 
    return 0; 
} 

/** 
this function 
input: 
output: 
*/ 
void searchingFunc(int arr[],int number,int specialNumber) 
{ 
    int i = 0; 
    while ((i < number) && (specialNumber != arr[i])) 
    { 
     i++; 
    } 

    if (i < number) 
    { 
     printf("the number found\n"); 
    } 
    else 
    { 
     printf("the Number not found\n"); 
    } 
} 

/** 
this function 
input: 
output: 
*/ 
void placesOfNum(int arr[],int number,int specialNumber) 
{ 
    int i = 0; 
    for(i=0;i<number;i++) 
    { 
     if (specialNumber== arr[i]) 
     { 
      printf("in the %d\n",i+1); 
     } 
    } 

} 


/** 
this function 
input: 
output: 
*/ 
int evenPlaces(int arr[],int number,int specialNumber) 
{ 
    int i=1,sum=0; 
    for(i=1;i<=number;i+2) //because the counting start from 0 
    { 
     sum = sum + arr[i]; 
    } 
    return sum; 

} 

功能的工作，但到了最後，它停止工作，不打印的最後數字 - 偶數的總和。請幫助我，謝謝

Answer 1

在evenPlaces功能，你沒有更新i在for循環。您還必須將i<=number更改爲i < number。

變化

for(i=1;i<=number;i+2) 

到

for(i = 1; i < number; i = i+2) {}
