small_ticket is on a distinguished road

there are some errors but where??

hi every body i am sending a piece of code which is a part of my program. there is no problem in the compilation (except a warning C4013: 'calloc' undefined; assuming extern returning int ) but this part does not working properly actually this must have to print a letter matrix like:
d f r t
a t k l
v a n d
s e i c
this matrix is in the file and must be printed to the screen but it doesn't it prints something strange like :
d f r
a t
v
n d
s e i c

and one more problem when i write argv[1] for opening the file it does not open but as i put below when i write the files name to the code it works!!
if you can help me i will be very happy have a nice day!!!
CPP / C++ / C Code:
if(  (fptr = fopen( "deneme.txt","rb")) == NULL ) 
	{
		printf("the file could not be found!!\n");
		turn:	//label
		do
		{
			printf("please enter a valid file path:");
			printf("if you do not want to play the game just write EXIT");
			scanf("%s",path);
			if(!(strncmp(path,exit,4))){			//if the user does not want to play anymore 
				printf("you know! if you do not want to play go and find a more interesting game!");
				break;
			}
		}
		while((fptr=fopen( path ,"rb"))==NULL);			//if the file could not be found or the path does not correct ask the user to enter a valid path
	} else {
		fscanf(fptr, "%d", &n1); //height
		
		fscanf(fptr, "%d", &n2);	//width	
		matrix=(char**)calloc(n1,sizeof(char *));	//dynamic memory allocation for the matrix
		for(m=0;m<n1;m++){
			matrix[m]=(char*) calloc(n2,sizeof(char));
		}
		for(row=0;row<=n1;row++) {
			for(col=0;col<=n2;col++){
				do
				{
					c = fgetc(fptr);
				}
				while(c == ' ' || c=='\n');
				if( isalpha(c) == 1){
					printf("There is an unvalid character in the letter matrix:\n");
						goto turn;
				}
				matrix[row][col] = c;
				printf("%c ",c);
				counter++;
				if(counter%n1==0){
					printf("\n");
                                  }
                           }
                     }

i have put the main part i think the mistake is in the part that i wrote and i have attached the file that i use in this program
CPP / C++ / C Code:
int main (int argc, char *argv[])
{
	FILE *fptr;
	char path[40];
	int start[1];
	int Start[1];
	char exit[5]="exit";
	char c;
	int n1,n2,number_of_words,number_of_rows=0,number_of_col=0,i,k,m,counter=0;
	char **words;   //words that will be searched in the matrix
	int row,col;
	char **matrix;
	if(  (fptr = fopen( "deneme.txt","rb")) == NULL ) 
	{
		printf("the file could not be found!!\n");
		turn:	//label
		do
		{
			printf("please enter a valid file path:");
			printf("if you do not want to play the game just write EXIT");
			scanf("%s",path);
			if(!(strncmp(path,exit,4))){			//if the user does not want to play anymore 
				printf("you know! if you do not want to play go and find a more interesting game!");
				break;
			}
		}
		while((fptr=fopen( path ,"rb"))==NULL);			//if the file could not be found or the path does not correct ask the user to enter a valid path
	} else {
		fscanf(fptr, "%d", &n1); //height
		
		fscanf(fptr, "%d", &n2);	//width	
		matrix=(char**)calloc(n1,sizeof(char *));	//dynamic memory allocation for the matrix

it probably has to do with the variable n1 you are reading it using fscanf, it might be reading a wrong value and then you are using n1 to allocate memory. sorry i can't be more specific or helpful as i'm not much of a c guy and have never used c memory allocation or file i/o functions before.


EDIT: it might also be this statement here: number_of_words=fgetc(fptr);
i assume it's supposed to get the filesize of fptr.
