I have the following code in C where I attempt to access elements of a two D int array

include <stdio.h>

include <time.h>

void main ()
{

int tr_nextstate[8][2] = {{0, 4}, {4, 0}, {5, 1}, {1, 5}, {2, 6}, {6, 2}, {7, 3}, {3, 7}};
int i, j,next_state=0;

clock_t start, end;
double cpu_time_used;
start = clock();

for (i = 0; i < 100000000; i++)
{
j = i % 2;
next_state = tr_nextstate[next_state][j];

}
end = clock();

cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC*1000;
printf("fun() took %f milliseconds to execute \n", cpu_time_used);

}

I have the same code in go :

package main

import (
"fmt"
"time"
)

func main() {
tr_nextstate := [][]int{{0, 4}, {4, 0}, {5, 1}, {1, 5}, {2, 6}, {6, 2}, {7, 3}, {3, 7}}

next_state := 0
var j int
startTime := time.Now()
for i := 0; i < 100000000; i++ {
    j:= i % 2
    next_state = tr_nextstate[next_state][j]

}
fmt.Printf("\nTime Elapsed : %v", time.Since(startTime))

}

When I run both the codes in my machine.
C - code gives a runtime of roughly 400 milliseconds
Go-code gives a runtime of roughtly 550 milliseconds

Can anyone throw light on why so?

My machine runs kubuntu 15.04 with i5 @2.4GHz with 16GB RAM
