any sort(numbers, strings, names, etc. ) store them into an array and print them out in reverse order into an output file. Could someone please get me started?

1) Look in the FAQ for file I/O
2) Look up sorting routines
3) The rest is easy
4) Gratz on being the 300th member!

I didn't test this but it should be right or else close to perfect or whatever the hell...Code://open the file FILE *fptr = fopen(filename,"r"); if(fptr == NULL) exit(1); //read input int i_array[20]; int i=0; while(fscanf(fptr,"%d",&i_array[i]) != NULL) { ++i; if(i >= 20) break; } --i; while(i > 0) { printf("%d\n", i_array[--i]); }
I compile code with:
Visual Studio.NET beta2
