C program read input file and output with "\n" new line every 50 characters -

void filecopy(file *ifp, file *ofp) {   int c;    while((c = getc(ifp))!= eof)     putc(c,ofp); } 

so, have try:

void filecopy(file *ifp, file *ofp) {   int c;   int count = 0;    while((c = getc(ifp))!= eof)     if(count == 50){      putc("\n",ofp);//this didnt work      count = 0;      }     putc(c,ofp); } 

am supposed use type of pointers? im not c pointers, know? thank you.

your putc attempting output string, pointer. putc takes initial 8 bits char of variable, not \n in case.

you want (note single quotes):

putc('\n', ofp); 

if using windows, may need output \r\n desired result.

finally, loop isn't testing every 50 characters, it's outputting value on each loop iteration. assume have done test.
