Error in my code in my C program ---

The goal is to print the sum of sophie germain numbers under a certain range. I'm having trouble accessing the ''i'' values that I need to count in order to establish how many prime numbers I have under a certain range. This is my code now and it doesn't give me access to the i values to count. I underlined the problem.

i.e if I were to enter r = 2, there should be an output value of 3,10 for the count.

#include #include #include

int main() { int prime, flag; int r, i,n,k,j; int low, high, count, range; int sg; high = pow(10,r); int A[high]; //Determining what the range will be printf("Please enter integer r "); scanf("%d", &r); printf(" ");

/*Finding prime numbers in range*/ high = pow(10,r);

for (i = 2; i <= high; i++){ flag = 0; for (n = 2;n <= i/2; n++){ if (i%n==0){ flag++; break; } } if (flag == 0 && i!= 1){ //Testing for germain prime numbers sg = 2*i +1; for (k = 2;k <= i/2; k++){ if (sg%k==0){ flag++; break; } } if(flag==0 && sg!= 1){ printf("-%d- ", i); } } } for (j = 1; j <= r; j++){ range = pow(10,j); if (i > range){ count++; printf("%d ", count); } } return 0; }
