To initialize a for loop with char, you first need to declare a variable of type char to hold the initial value. The syntax for the initialization statement is as follows:

for (char c = 'a'; c <= 'z'; c++) { // Loop body }

In this example, the loop will start with the variable 'c' initialized to the value of 'a', and will continue to run as long as 'c' is less than or equal to 'z'. At the end of each iteration of the loop, the value of 'c' will be incremented by one, using the '++' operator.
