c - C语言中如何计算数组的元素个数？

Question

#include <stdio.h>
#include <string.h>
int main()
{
char name[32][32];
char input[32];
int number;
int i;

for(i=0;i<10;i++)
{
    fgets(input,sizeof(input),stdin);
    sscanf(input,%s,name[i]);

}  

//assume that we don't know variable name have 10 element of arrays.

//function to count how many elements of arrays to stored at number.

for(i=0;i<number;i++)
{
    printf("%s",name[i]);
}
}

什么函数可以计算数组的元素？

Answer 1

将目标字符串初始化为 0，然后在打印时检查它们是否不为空怎么样？

#include <stdio.h>
#include <string.h>
int main()
{
    char name[32][32] = {0};
     ...
     for(i=0;i<32;i++)
     {
         if(name[i][0]!='\0')
             printf("%s",name[i]);
     }
 }
