Write a c program that accepts a text as input and generataes as output the following results. i. the total number of alphanumeric characters. (lower case upper case numbers) ii. the total number of letters and teir frequency with respect to the total number of alphanumeric characters. iii. the total number of digits and their frequency with respect ot the total number of alphanumeric characters. iv. the total number of words. v. the total number of words starting with "ing" and their frequeny with respect to the total number of words. vi. the total number of words ending with "ing" and their frequency with respect to the total number of words. vii. the total number of words having "ing" in the middle and their frequency with respect to the total number of sequences of three alphanumeric characters me asap. need this by tomorrow

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
