Wrong output from an array - c

Question

I've been running this for a couple of hours, and continue to get the wrong output, and can't seem to find out why. It seems as if everything should work, but I consistently get a weird character for the first time I implement this, and the tokens are not getting moved around in the way that they should be. This is just practice code, to be implemented in assembly language.
char get_line(void){
//Char array, buf space 80, int array, hold the numerical value,
char arr[80];
int int_arr[80];
char arr_print[80];
//Two points to compare whether the value in the given array changed.
int compare;
int compare_2;
//Array points, indexes and size counter.
int count = -1;
int i = 0;
int j = 0;
int k;
gets(arr);//Unsafe version of code, but for this implementation negligible.
while( (arr[i] != NULL) && (i < 80) && arr[i] != '\n'){
//Runs through and sets the value based on specs, #'s =1, alpha =2, ...
//For the comparison with the below code.
if(isalpha(arr[i])){
int_arr[i] = 2;// printf("%c: 2", arr[i]);
compare = 2;
}else if(isdigit(arr[i])){
int_arr[i] = 1;// printf("%d: 1", arr[i]);
compare = 1;
}else if(arr[i] == '$'){
int_arr[i] = 5;// printf("%c: 5", arr[i]);
compare = 5;
}else if(arr[i] == '#'){
int_arr[i] = 6;// printf("%c: 6", arr[i]);
compare = 6;
}else if(arr[i] == '(' || arr[i] == ')' || arr[i] == ',' ||
arr[i] == '.' || arr[i] == ':'){
int_arr[i] = 4;// printf("%c: 4", arr[i]);
compare = 4;
}else if(arr[i] == '*' || arr[i] == '+' || arr[i] == '-' ||
arr[i] == '/'){
int_arr[i] = 3;//printf("%c: 3", arr[i]);
compare = 3;
}else if(isspace(arr[i]))
int_arr[i] = 5;//Ignore the spaces in this implementation.
/*
Runs the comparison point to assure that the
tokens are matched up and grouped as needed.
*/
if(compare_2 == 0 || (compare != compare_2)){
if(compare_2 != 0){
for(k=0; k<=j ;k++)
printf("%c", arr_print[k]);
j=0;
}
printf("\t\t%d \n", compare_2);
compare_2 = compare;
}else if( isspace(arr[i]) == 0 ){
arr_print[j] = arr[i];
// printf("\t\t\t\t\t%c | %d\n", arr_print[j],j);
j++;
}
i++;
count++;
}
printf("\n\n");
//Code for previous implementation in C
for(i=0; i<80 && arr[i] != NULL; i++)
printf("%c", arr[i]);
printf("\n");
for(i=0; i< count+1; i++)
printf("%d", int_arr[i]);
printf("\n");
if(i == 0 || count == -1) return '#';
return arr[count];
}

I think this is what you needed
Try this code
char get_line(void)
{
//Char array, buf space 80, int array, hold the numerical value,
char arr[80];
int int_arr[80];
char arr_print[80];
//Two points to compare whether the value in the given array changed.
int compare=0;
int compare_2=0;
//Array points, indexes and size counter.
int count = -1;
int i = 0;
int j = 0;
int k = 0;
int l = 0; // I add an int l for
gets(arr);//Unsafe version of code, but for this implementation negligible.
//while( (arr[i] != NULL) && (i < 80) && arr[i] != '\n'){
while( i < 80 && arr[i] != '\0')
{
//Runs through and sets the value based on specs, #'s =1, alpha =2, ...
//For the comparison with the below code.
if(isalpha(arr[i]))
{
int_arr[i] = 2;// printf("%c: 2", arr[i]);
compare = 2;
}
else if(isdigit(arr[i]))
{
int_arr[i] = 1;// printf("%d: 1", arr[i]);
compare = 1;
}
else if(arr[i] == '$')
{
int_arr[i] = 5;// printf("%c: 5", arr[i]);
compare = 5;
}
else if(arr[i] == '#')
{
int_arr[i] = 6;// printf("%c: 6", arr[i]);
compare = 6;
}
else if(arr[i] == '(' || arr[i] == ')' || arr[i] == ',' || arr[i] == '.' || arr[i] == ':')
{
int_arr[i] = 4;// printf("%c: 4", arr[i]);
compare = 4;
}
else if(arr[i] == '*' || arr[i] == '+' || arr[i] == '-' || arr[i] == '/')
{
int_arr[i] = 3;//printf("%c: 3", arr[i]);
compare = 3;
}
else if(isspace(arr[i]))
int_arr[i] = 5;//Ignore the spaces in this implementation.
/*

*/
if(compare_2 == 0 || (compare != compare_2))
{
if(compare_2 != 0)
{
for(k=0; k<=j ;k++)
printf("%c", arr[l+k]); // arr_print replaced by arr
j=0;

count++;
}
