a) Write a program that will determine who the killer is, by matching this fragment to the DNA of the Suspects. Note that this fragment has to match perfectly with a part of the DNA of the suspect.

fragment is GCGCA
suspect DNA is which ever string suspect array is equal to
Code:
#include <stdio.h>
#include <math.h>
#include <string.h>

char suspect(int);
int main()
{
	char suspect[i][17];
	int i=0;
	printf("the suspect that comitted the crime is %s",suspect[i]);
}
char suspect(int i)
{
	suspect[1]="ATTCGCTTATTCCGAC";
    suspect[2]="AAGCGCTAACCGCTAG";
	suspect[3]="CAGCGCAAACGCCGTT";
	suspect[4]="GCGCTCAAAGGCTTAA";
	if(suspect[i]=="GCGCA")
	{
	return(i);
	}
}
i get the error
error C2109: subscript requires array or pointer type
where ever suspect is
