Sorting letters C programming

I'm trying to make the letters of a matrix sort alphabetically and then be written out in a single string.For instance you type ten words,which are then stored in an array,and every letter has its place in the matrix then,right?But after I've written the words I want to bunch all the letters of all words together and then type all the letters out in alphabetical order.This is what I have so far:

#include <stdio.h>
#include <conio.h>

int main(void){
    int i, j, k, f, n, m; 
    //was trying out various things,that's why I have so many useless ints up there
    char word[10][15],temp;

    for(i=0;i<=9;i++)
    {
        printf("Type in wword number %d: ", i+1);
        gets(word[i]);
    }

    for(k=i-1;k>=0;k--)
    {
        for(m=0;m<k;m++)
            if(word[k][f] > word[m][n])
            {
                temp=word[k][f];
                word[k][f]=word[m][n];
                word[m][n]=temp;
            }
    }
    printf("Letters alphabetically sorted: ");
    for(i=0;i<=9;i++){
        for(j=0;j<=14;j++){
            printf("%d",word[i][j]);
        }
    }
    printf("\n");
    getch();
}

I'm still in the process of learning about matrixes and I've gotten pretty familiar with arrays by now.But the sorting thing is confusing me,this was my attempt but it doesn't work.It lets you write all the words,and then it crashes.

What am I doing wrong here?And how do I correct it?

I think this will work..Please excute and tell me..

void main()    
{

char word[10][15],temp,sorted_word[15];

int i,j,ii,k,l=0;

for(i=0;i<=9;i++)             
{                  
printf("Type in wword number %d: ", i+1);                 
gets(word[i]);            
}


for(i=0;i<=9;i++)

{

for(j=0;word[i][j]!='\0';j++)

{

ii=i;
for(k=j+1;1;k++)
{
if(ii==9 && word[ii][k]=='\0')
break;
if(word[ii][k]=='\0')
{
ii++;
k=0;
}
if(word[i][j]>word[ii][k])
{
temp=word[i][j];
word[i][j]=word[ii][k];
word[ii][k]=temp;
} 
}
sorted_word[l++]=word[i][j];
}

}

sorted_word[l]='\0';

printf("%s",sorted_word);

getch();

}

here the

for(i=0;i<=9;i++)
{ printf("type in wword %d: ",i+1);
gets(word[i]); 
}

gets (word[1]);

stores the value from word[1] onwards but where as the character array starts from word[0].

may be this is not the full solution for u problem this issue may help u in solving your doubt.

f,n are uninitialized. It has garbage and is the reason for crashing at this point.

for(k=i-1;k>=0;k--)
{
    for(m=0;m<k;m++)

    if(word[k][f] > word[m][n]) // f,n are uninitialized and are error prone

In your code here:

        temp=word[k][f];
        word[k][f]=word[m][n];
        word[m][n]=temp;

the variables n and f are used uninitialised. That will most likely be the cause of the crash.
