WebAccording to the iteration count formula, the loop will be executed n = (11 - 1 + 2) / 2 = 6 times. Note that this is also the initial value of the iteration count (n = 6). With J= 1, the first pass through the loop is completed. The value of J is incremented to J= 3; the iteration count is now n = 5, and the second pass is completed. spice of life cafe hamiltonWebIf logical-expression-1 is .FALSE., Fortran evaluates logical-expression-2 and executes statements-2 and so on.
