I am trying to get a deeper understanding to how for loops for different data types in Python. The simplest way of using a for loop an iterating over an array is as I also know that I can What I would like to know is what this does or And what happens if I … Read more
I have a list of variables name “comorbid_names”. And I want to select people who have those comorbidities in “comorbidities”. However, I want to select the variable names if they are true. For example patient 1 has “chd” only, therefore only that will be displayed as TRUE comorbid_names [1] “chd” “heart_failure” “stroke”[4] “hypertension” “diabetes” “copd”[7] … Read more
I’m trying to write a procedure in assembly that sorts an array using bubble-sort algorithm but I’m having a problem which is: In line 22, when the first iteration executed nothing is wrong, program loads array[i+1] perfectly into registrar $a1 and if the swap condition is valid, program swaps without any problem. However, in the … Read more
&arr gives an array pointer, a special pointer type int(*)[5] which points at the array as whole. arr, when written in an expression such a int *q = arr;, “decays” into a pointer to the first element. Completely equivalent to int *q = &arr[0]; In the first case you try to assign a int(*)[5] to … Read more
word_array[0] is a char, whereas word1 is a char *. Your character is not able to hold an address. An array of strings might look like it: If you rather want an array of pointers to your strings: And then: Maybe you should read this.
It can have 3 distinct meanings: ‘<<‘ as an ordinary method In most cases ‘<<‘ is a method defined like the rest of them, in your case it means “add to the end of this array” (see also here). That’s in your particular case, but there are also a lot of other occasions where you’ll encounter … Read more
Same way as you would in JavaScript. Note that this sets the element to undefined. Better to use the Array.prototype.splice function:
.space Len directive instructs the assembler to reserve Len bytes. As every word has 4 bytes, when Len is 20 you are instructing the assembler to reserve 5 words. For example if you have then other_data will be 20 bytes after array address. Due to architectural constraints in MIPS you may need to also instruct the assembler to align the … Read more
Here are some various bits of code you can use to accomplish this. Create array Increment a position in the array Print histogram Here are some helper functions as well. Code should be modified as needed.
I am trying to create an array of strings in C. If I use this code: gcc gives me “warning: assignment from incompatible pointer type”. What is the correct way to do this? edit: I am curious why this should give a compiler warning since if I do printf(a[1]);, it correctly prints “hmm”.
