I need help! How to fix my code?

My code

#include<stdio.h>

int main(){
char filename[100];//variable to store filename in
char line[10000],ch=' ';//input buffers
int idx=0;
//input of filename
printf("\n\tEnter File Name: ");
scanf("%s",&filename);
FILE *input;//pointer to file
if((input = fopen(filename,"r"))){
while(ch != EOF){//until end of file is reached
ch = fgetc(input);//read next character
if(ch=='\n' || ch==EOF){//if it is a newline character,print the line
printf("\t");
int i;
for(i=0;i<idx;i++)
printf("%c",line[i]);
printf("\n");
idx=0;
}
else{//else add the current character to the buffer/array of char
line[idx]=ch;
idx++;
}
}
}
else{
printf("\tThe file can't be open. File does not exits.");
}
fclose(input);//close the file
return 0;
}
