Hi all, i have written below code and it is not sussed, I got error with all tests.
Can you help me to understand why?

#include <stdio.h>
#include <string.h>
int main() {
char line[150];
fgets(line, sizeof(line), stdin);
for (int i = 0, j; line[i] != '\0'; ++i) {
while (!(line[i] >= 'a' && line[i] <= 'z') && !(line[i] >= 'A' && line[i] <= 'Z') && !(line[i] == ' ') &&!(line[i] == '\0')&&!(line[i] == '\n')) {
for (j = i; line[j] != '\0'; ++j) {
line[j] = line[j + 1];
}
line[j] = '\0';
}
}
for (int i = strlen(line); i >= 0; --i){
printf ("%c", line[i]);
}

Answer 1

i wrote the code another way and it worked yet i don't know why this one is not passing test cases so i cant really help out , i hope some one with better understanding can find out why

Answer 2

You just forgot to add
} at the end :)

Answer 3

The } at the end is to close the for loop
The main {}
Is not closed

Answer 4

Can you copy the task content here?

Answer 5

Thanks, the issue was on latest for loop:
I just add -1 to initial i value.

for (int i = strlen (line)-1; i >= 0 b --i)

Answer 6

Thx for sharing how it got fixed

Answer 7

dareen moughrabi this is copy error, the code run and print the letters only on reverse.
But it return error!

Answer 8

Let say the input is "1o2l3l4e5H6"
The output is "Hello"
It work also with special letters.

Answer 9

You are a secret agent, and you receive an encrypted message that needs to be decoded. The code that is being used flips the message backwards and inserts non-alphabetic characters in the message to make it hard to decipher.

Task:
Create a program that will take the encoded message, flip it around, remove any characters that are not a letter or a space, and output the hidden message.

Input Format:
A string of characters that represent the encoded message.

Output Format:
A string of character that represent the intended secret message.

Sample Input:
d89%l++5r19o7W *o=l645le9H

Sample Output:
Hello World
