//String-without string handling function
//Write a program to reverse a string without using string handling function.

/*Algorithm:
step1: Take a string as input and store it in the array of characters
step2: Create 2 counter variables i and n where 'n' is used to store the length of the string
step3: Count the length of the string using strlen function
step4: Using for loop write the condition to reverse a string
step5: Print the result*/

//Write a program to check that a string is palindrome.

/*Algorithm:
step1: Take a string as input and store it in the array of characters
step2: Create 3 counter variables i,c and j
step3: Count the length of the string using strlen function
step4: Using for loop write the condition to store the new value in the variable i and in the for loop using if statement write the condition to check whether the string is palindrome or not
step5: Using the if-else statement write the condition to print whether the string is palindrome or not*/

//Write a program to count number of characters and number of words in line of text.
//Output should print the number of characters and words

/*Algorithm:
step1: Take a string as input and store it in the array of characters
step2: Create 3 counter variables i,c, and w where 'c' is used to the number of characters in a string and 'w' is used to store the number of words
step3: Using while loop write condition to check whether the string is empty or not, if it empty then it will terminate the code and it will print the result
step4: Using the if-else statement write the condition to check whether the string contains space or not, if it contains a space then the code will count the number of characters and words after space
step5: Print the result*/
