I was asked the following?
Complete the body of the following function:
/** Return the index in array data of the element closest to or
equal to value. The array data has exactly data_count
elements. */
size_t find_nearest (int value, const int* data, size_t data_count);
Any quick code? thanks a lot

为什么这种code也来求啊？是作业么？
就是个简单循环一遍的事情，都不涉及到多指针，自己还搞不定的话，以后能干活儿么？

【在 n*c 的大作中提到】

size_t find_nearest(int value, const, int * data, size_t data_count) {
size_t res = 0;
int tmp1 = 0;
int tmp2 = value;

if (0 == data_count)
return data_count;

for (size_t i = 0; i < data_count; i++) {
tmp1 = value >= data[i]? (value - data[i]):(data[i] - value);
if (tmp1 < tmp2){
tmp2 = tmp1;
res = i;
}
}

return res;
}
老朽多年不写C和C++了，也不知道对不，nodejs害人不浅啊

献丑了，不知道理解对不，请lz自己调试一下
int fabs(int var1, int var2);
size_t find_nearest(int value, const int* data, size_t data_count);
{
int index,indexValue, temp;
temp = fabs(value, data[0]);
indexValue = 0;
for(index=0; index < data_count; index++)
{
if(temp > fabs(value, data[index]))
indexValue = index;
}
return (size_t)indexValue;
}
int fabs(int var1, int var2)
{
retrun var1 >= var2? (var1-var2): -(var1-var2);
}
