Why is my program printing more prime no.s than those which are expected | Basic C Programming

https://code.sololearn.com/cQZudLLXtQpm/?ref=app I’ll be really grateful if some one out there spare some time to check my code and spot the error in this simple basic code.

The problem lies in this line 👇 scanf("enter a number %d", &n); If you work with that, then suppose you want to print prime numbers upto 20, your input should be "enter a number 20" You can try this instead scanf("%d enter a number", &n); Now you only need to input a number But it's better if you do this 👇 printf("enter a number \n"); scanf("%d", &n); #include <stdio.h> int main() { int n,i,j,k; printf("enter a number \n"); scanf("%d", &n); printf("Prime numbers are: \n"); for (i=2; i<=n; i++) { k=0; for (j=2; j<i; j++) { if (i%j==0) { k=1; } } if (k==0) { printf("%d\n", i); } } }

Baptiste E. Prunier Never thought use of scanf in a little different way can disturb the output so interestingly. Thank ypu
