 // b) What is the if statement used to check
 // c) Why is index++ being used?
 // d) What is the condition index < str.length used for?
+
+// a):
+
+// The index variable is initially set to 0.
+// Inside the while loop, index is incremented by 1 in each iteration using the index++ statement.
+// The purpose is to move through each character in the string, checking if it matches the target character.
+
+// b):
+
+// The if statement is checking if the character at the current index in the string (str[index]) is equal to the target character (char).
+// The condition is if (str[index] === char). If this condition is true, it means the target character is found at the current index.
+
+// c):
+
+// index++ is the post-increment operator, and it is used to increment the index variable by 1 after each iteration of the loop.
+// This is necessary to move to the next character in the string and avoid an infinite loop.
+
+// d):
+
+// The condition index < str.length is used as the loop condition.
+// The loop continues to iterate as long as the current value of index is less than the length of the string (str.length).
+// This ensures that the loop iterates through each character in the string, and it prevents going beyond the bounds of the string.
