help needed with c code [Solved]

https://code.sololearn.com/cBmOfvQaqv6W/#c Goldbach's conjecture code won't work properly. The prime numbers seem okay. Maybe something's wrong with the array I'm not sure..

you cannot loop till prime[count] as it is 47 in case user entered number as 50... So, you have definitely less numbers then 47 in array and you are going from i as 3 to 47... it should be as below: for(i=0;i<=count;i++){ for(j=0;j<=count/2;j++){ if((prime[i]+prime[j])==input) printf("%d+%d\n",prime[i],prime[j]); } }
