Mihail In your logic there should be -j in second loop. hafidz ridwan cahya See working code here https://code.sololearn.com/cJwF89aGgWSx/?ref=app

hafidz ridwan cahya In second loop after every iteration of 1st loop, size will reduce because of strlen(str) - j So when j = 0 then 2nd loop will iterate 5 times and print WORLD When j = 1 then 2nd loop will iterate 4 times and print WORL -------------------- -------------------- When j = 4 then 2nd loop will iterate 1 times and print W

Can you explain how nested for for loop here and -j logic work here?Mihail

since it doesn't ask to preserve the content, I would have solved it like that #include <stdio.h> #include <string.h> int main() { char arr[300]; scanf("%s", arr); for(int l=strlen(arr); l; arr[--l]='\0') printf("%s\n",arr); return 0; } https://code.sololearn.com/c66gsZCt5aU5/?ref=app if you want to preserve the string you can do so. two nested for loops with continuous calls to strlen are wasteful #include <stdio.h> #include <string.h> int main() { char arr[300]; scanf("%s", arr); char t='\0'; for(int l=strlen(arr); l; arr[--l]='\0'){ printf("%s\n",arr); arr[l]=t; t=arr[l-1]; } arr[0]=t; printf("%s\n",arr); return 0; } https://code.sololearn.com/ccP90RutFoSW/?ref=app

if you have a char array it would go something like this: int i,j; for(j=0;j<strlen(arr);j++) { for(i=0;i<strlen(arr)-i;i++) { printf("%c",arr[i]); } printf("\n"); }

You doesn't even need string.h header file. https://code.sololearn.com/c1uO8NjQYBrD/?ref=app

Sorry, I made a mistake in the second for loop. I fixed it now. int i,j; for(j=0;j<strlen(arr);j++) { for(i=0;i<strlen(arr)-j;i++) { printf("%c",arr[i]); } printf("\n"); }
