C Assignment

I am suppose to make a programme that counts the number of vowels in an input file. Can somebody please tell me what I am doing wrong on this assignment? PLEASE!?

<lj-cut text="PRoblem">

Here is what I am trying to print:

Sample output:

a: 48: ************************************************
e: 49: *************************************************
i: 48: ************************************************
o: 42: ******************************************
u: 17: *****************


Here is my code:

#include <stdio.h>

int main()
{
FILE* infile = fopen("vowels.in", "r");
FILE* outfile = fopen("vowels.out", "w");


int a,e,i,o,u,j;
a=0;
e=0;
i=0;
o=0;
u=0;
char current;

while(1)
{
fscanf(infile, "%c", &current);
if(current == "a");
a++ ;
if(current == "e")
e++ ;
if(current == "i")
i++ ;
if(current == "o")
o++ ;
if(current == "u")
u++ ;
if(feof(infile)) break;
}

fprintf(outfile, "a: %d: ", a);
for(j=0; j<=a; j++)
{
fprintf(outfile, "*");
}

fprintf(outfile, "\ne: %d: ", e);
for(j=0; j<=e; j++)
{
fprintf(outfile, "*");
}

fprintf(outfile, "\ni: %d: ", i);
for(j=0; j<=i; j++)
{
fprintf(outfile, "*");
}

fprintf(outfile, "\no: %d: ", o);
for(j=0; j<=o; j++)
{
fprintf(outfile, "*");
}

fprintf(outfile, "\nu: %d: ", u);
for(j=0; j<=u; j++)
{
fprintf(outfile, "*");
}


return 0;
}



Here are my errors:
