Is language hard to learn or VB hard to learn? Can anyone tell me? What should I learn to get starte

If you are not a computer science major, then learn VB, it is easy to learn, and you can use it after learning. Very good. But if you want to develop in software later, it's better to start with C.

The pointer can be said to be a major feature of C, many people accidentally understand it, in fact, you can understand what the pointer is by comparing the visual method. When the data storage in the C language does not have a pointer to intervene, it is directly operated, just like if you go to a building to find someone, the security guards bring people directly to you, and C accesses the data as well, but sometimes you just don't know the name of this variable, that is, you don't know what the person's name is, can you still find the data or person, that is, you can use a pointer in C to achieve it, which is equivalent to you don't know what the person's name is, but you know that he lives in that room (let's assume that a room lives in a person), The security guard can still bring people to you, and the same goes for C, if you point out that the data is in that location, the CPU can also find the data for you, the same way. And what's the benefit of this.,It's going to talk about arrays.,You have a bunch of numbers stored in a continuous memory unit.,Similar to your group of friends living in that building.,And it's living next to each other.,You have to call them out to play.,Just like you want to take out the data and use it.,Then I would have shaken the registration word one by one to the security guard.,Say which person and that person and so on to help me find it.,C can also be achieved through this method.,But it's obviously too troublesome.,If you know the room number where the first person lives.,And then for example, there are 10 people, So you just need to say help me call the next number to the number of people (referring to the continuous room number they live in), oh, it's easier for the security guard to do, because the name of the security guard may not be known, but the room number must be known, the same is true in c, you don't need to call these data one by one, directly know the address of their first data, and then count down one by one to say that the data in that location can be called by me, in fact, you give a variable, the CPU still has to find that number through the address, It's like if you tell the security guard the name of that person, he still has to find out which room he lives in. >>>More

Definition of a for loop.

for(the initial value of the variable; termination of operating conditions; The initial value of the first cycle i is 0, and it runs until i=3 stops i=2, and the condition is still satisfied, and the loop body is still executed, and the step size is 1+1 each time >>>More

Hey! This is a very simple function to write, Your Excellency is estimated to have just learned data structures, now learn sorting, lookup, it's easy to give me a reward of two hundred points, I'll help you write it right away. >>>More

It's called the [batch] program, in fact, don't think that the program you mentioned above to deal with garbage is really powerful, it's amazing, when you have learned DOS, that program can be said to be a very simple thing; >>>More
