What is the C File Function to delete a letter say, 'A' in a File. Anything like fgetc, fputc etc?

I have developed a program for Bitstuffing. It scans for characters from a file, and if it encounters five 1's continuously, it will append a '0' after it and write to a new file. This concept is called Bit Stuffing. Now, I need to know how to remove that '0' in the file I wrote.


==##CODE ##==


FILE *fp1,*fp2; //Couple of File pointers


int i=0; //Counter


char c; //variable to get char from File


fp1=fopen("bit.txt","r"); //Open file in Read mode


fp2=fopen("b1.txt","w");//Open file in Write mode


while(!feof(fp1))


{


c=fgetc(fp1); //scan char by char till EOF


if(c=='1') i+=1;


else if(c=='0') i=0;


fputc(c,fp2);


if(i==5)


{


fputc('0',fp2); //append 0 after five 1s and reset i


i=0;


}


fclose(fp1);


fclose(fp2);


==## END OF CODE ##==


bit.txt content: 111111


b1.txt content: 1111101





How to remove that 0?





Help would be much appreciaited.

Try this method:


1) Read b1.txt


2) Check for five 1's write the contents of b1.txt into a new file temp.txt


3) Once you have written it . delete b1.txt


4) rename temp.txt as b1.txt





Program


fp3=fopen("temp.txt","w");


rewind(fp2);


i=0;


while(!feof(fp2))


{


if (i%26lt;=5)


{


c=fgetc(fp2);


fputc(c,fp3);


if (c==1)


i++;


if(i==5)


i=0;


}


}


fclose(fp2);


fclose(fp3);


remove("b1.txt");


rename("temp.txt","b1.txt");
