Counting DNA nucleotides in C
I would change the loop to a:
while (c=fgetc(input))
then use an array of 4 for the sums:
unsigned int nucleotides[4];
int n; /* index into nucleotides, per the switch below: 0=a, 1=c, 2=g, 3=t*/ … then index into the nucleotides and increment as:
switch (c)
{
case 'A': n=0; break;
case 'C': n=1; break;
case 'G': n=2; break;
case 'T': n=3; break;
}
nucleotides[n]++;
Finally …
