What's wrong in this program to remove extra spaces?

I tried to write a program to remove extra spacing. But it never returned the desired output. Can I know what's wrong here and how I can correct it?

#include<stdio.h>

main()
{
    char strin[150];
    int n,i;
    printf("Number of words : ");
    scanf("%d",&n);
    printf("Enter Input: ");
    for(i=0;i<n;i++)
    {
        scanf("%c",&strin[i]);

    }
    for(i=0;i<n;i++)
    {
        if(strin[i]==" ")
            continue;
        else
            printf("%c",strin[i]);
    }
}

Also I tried using %s instead of %c (with string.h header) but the run cmd crashed upon running it. Why does it crash?

If you want to remove all spaces in the string and store it instead of just printing it, you can use this simple function:

void rmspaces(char *str)
{
    const char *dup = str;
    do {
        while (isspace(*dup)) {
            ++dup;
        }
    } while (*str++ = *dup++);
}

You can then call the function like this:

rmspaces(str);

Use ' ' instead of " " for checking a single character.

Use strcmp() to check more than one characters or whole string
