How can i take multiple string input in c?

I am trying to learn string in c. I have written this program. I want this program will terminate for a particular word (press ENTER after typing the word). Its Compile well but after given input when I pressing enter it shows me this message: test.exe has stopped working. Here "test" is the name of my program. Please help me to understand this.

#include<stdio.h>
#include<string.h>
#include<stdlib.h>

int main()
{
    int i, j;

        char *str[10];
        for(i=0; i<10; i++)
        {
            //gets(str[i]);
            scanf("%s",str[i]);
            if(str[i]=="man") break;
        }


        for(j=0; j<10; j++)
        {
            printf("%s\n",str[j]);
        }   

    return 0;
}

For comparing strings in C, you can use strcmp function. For example:

if(strcmp(str[i],"man") == 0){
    # write your code here
}

And for initialization, do as follows.

char *str[10];
for(i=0; i<10; i++){
    str[i] = malloc(sizeof(char) * 1024);
}

You can also do as following.

char str[10][1024];
for(i=0; i<10; i++){
    scanf("%s", str[i]);
}

Alternative: If you want to declare str as char **str, you can follow the following approach.

char **str = malloc(10*sizeof(char*));
for(int i=0; i<10; i++){
    str[i] = malloc(sizeof(char) * 1024); // buffer for 1024 chars
}
