I am trying to find out the length of an string using strlen() but it seems to not working properly my code is below with the input i given
#include using namespace std; int main() { long long T,a,b,c,e; scanf("%lld",T); long long M[T]; for(a=1;a<=T;a++) { scanf("%lld",&M[a]); c=M[a]; long long l[c],d[c],r[c]; for(b=1;b<=c;b++) { scanf("%lld%lld",&l[b],&d[b]); r[b]=l[b]*d[a]; e=strlen(r); printf("%d",e); } } return 0; } Input 1 1 100 100
Can you tell me where i am going wrong?
