##this a bubble sort program, reads input from file and write the sorted data in the output file### but i want to converted it in assembly code,,,GCC in linux converted the code given after this…can anyone hepl me???

#include
int main(void){
int n, i, j, tmp;
int A[10000];
FILE *file, *file2;
file = fopen(“input.txt”, “r+”);
file2 = fopen(“output.txt”, “w+”);
if(file==NULL){
printf(“Error: can’t open file to read.\n”);
return 1;
}
if(file2==NULL){
printf(“Error: can’t open file to write.\n”);
return 1;
}
else{
i=0;
while(!feof(file)){
fscanf(file,”%d”,(int *)&A[i]);
i++;
}
n=i-1;
}
fclose(file);
for(i=0; i
for(j=i; j
if(A[j]
tmp=A[j];
A[j]=A[i];
A[i]=tmp;
}
}
}
for(i=0;i
fprintf(file2,”%d\n”,A[i]);
fclose(file2);
return 0;
}

this is totally a rubbish output…please help.
I need to run it in WINDLX…but GCC conversion does not support basic file operations in C. it also does not support scanf() function…
ok, i am agree with the code procedure…but if this is an converted assembly code…why it is not running in WINDLX??? is there any version problem?
Thats right….the GCC conversion is not compatible for WinDLX….as they are of different set of instructions. Thanks a bunch for your replies…
