如何通过将引用传递给C中的函数来获取输出字符串数组？

Question

When I am trying to get my output using the code in bellow, It's always stopped. But why and how can I solve this issue? Thanks in advance.

#include<stdio.h>
void nameView(char* []);

int n, i, j;

int main(){

   char name[10][10];

    printf("Enter case: ");
    scanf("%d", &n);

    for(i=0; i<n; ++i){
        printf("Enter Name: ");
        scanf("%s", name[i]);
    }

    nameView(&name);


    return 0;
 }

  void nameView(char *b[]){

   for(i=0; i<n; ++i){

        printf("\n%s", *b[i]);
    }
 }

Programmed has stoped but when I replaced

    for(i=0; i<n; ++i){

        printf("\n%s", *b[i]);
    } 

Insead of "nameView(&name)" in main function it's work.How can I output by passing reference in "nameView()" function

Answer 1

As was mentioned in the comments, your function prototype:

void nameView(char* []);

Does not match the definition:

void nameView(char *b){

Additionally, the argument you pass in ( &name which is `char (*)[10][10], ie a pointer to a 2D array) doesn't match either parameter.

You need to declare and define your function like to take a 2D array of 10x10 chars :

void nameView(char b[10][10]){

Or equivalently, a pointer to an array of size 10:

void nameView(char (*b)[10]){

And call it with the name of the array:

nameView(name);

The following proposed code:

1. implements the corrections to the problems highlighted in the comments.
2. cleanly compiles
3. performs the desired functionality
4. checks for errors
5. eliminates the (very undesirable) global variables
6. limits the scope of the variables
7. documents why each header file is included

and now the code:

#include <stdio.h>  // scanf(), printf(), perror()
#include <stdlib.h> // exit(), EXIT_FAILURE

#define MAX_NAMES  10
#define MAX_LENGTH 10


// prototypes
void nameView(char [][ MAX_LENGTH ], int);


int main( void )
{
    char name[ MAX_NAMES ][ MAX_LENGTH ];
    int n;

    printf("Enter case: ");
    if( 1 != scanf("%d", &n) )
    {
        perror( "scanf for number of names failed" );
        exit( EXIT_FAILURE );
    }

    // implied else, scanf successful

    EDIT:
    //if( 0 < n || n > MAX_NAMES )
    if( n < 0 || n > MAX_NAMES )
    {
        printf( "invalid entry for Name count, must be in the range 1...10\n" );
        exit( EXIT_FAILURE );
    }

    // implied else, 'n' contains a valid value

    for(int i=0; i<n; ++i)
    {
        printf("Enter Name: ");
        if( 1 != scanf("%9s", name[i]) )
        {
            perror( "scanf for name failed" );
            exit( EXIT_FAILURE );
        }
    }

    nameView(name, n);
    return 0;
} // end function: main


void nameView(char b[][ MAX_LENGTH ], int n)
{
    for(int i=0; i<n; ++i)
    {
        printf("\n%s", b[i]);
    }
} // end function: nameView
