Nov 25, 2013 · Given a pointer to an array of char* pointers terminated with an empty string (or NULL), delete all strings in the pointer array that contain word. The resulting potentially compacted array is the return value of the function.

Jan 10, 2025 · In C, an array of strings is a 2D array where each row contains a sequence of characters terminated by a ‘\0’ NULL character (strings). It is used to store multiple strings in a single array. Let’s take a look at an example:

Feb 11, 2025 · In this lab, you will learn how to manipulate arrays and strings in C by implementing operations such as adding, searching, deleting, and listing contacts in a simple contact management app. You will also practice debugging common array and string issues, sorting, and searching data effectively.

Apr 15, 2010 · A couple of ways come to mind. Given that strings in C are usually terminated by an ASCII zero, the easiest would be to set the first byte to zero. Another way might be to use memset() to set the whole string to zeros.

Sep 24, 2015 · const char *string[5]; string[0] = "White"; string[1] = "Black"; string[2] = "Blue"; string[3] = "Red"; string[4] = "Yellow"; gets(string); printf(//);

In your case, removing a part of the string can be done by a simple memory move: void removeString (char string[], int start, int length) { int from = start + length; // You should do some verifications here, like start < string length, etc. while (string[from] != 0) string[start++] = string[from++]; string[start] = 0; }

Nov 20, 2020 · For example, to delete a string from an array of strings means to delete all character content from that area of memory. i.e. either setting the first character of the string to NULL , or memset() the entire array element to NULL , eg: memset(array, 0, sizeof array); .

Jul 21, 2022 · Use strcpy() to copy strings. Or change it to an array of pointers, and allocate the strings dynamically. Although arrays are implemented with pointers in C, the compiler will treat them the differently. As you can see in your own example the line n [i] = n [i+1] causes the error you see, because n [i] is an array of chars.

Aug 1, 2010 · Sort the array with an algorithm like qsort (man 3 qsort in the terminal to see how it should be used) and then use the function strcmp to compare the strings and find duplicates

Feb 18, 2019 · I want to move each string, that I want to delete, to the end of the array and then delete it, but not sure when the "realloc" should happen. char* check=malloc(sizeof(char)*100); int deleted; int i,j,g,h; for(i=0;i<n;i++){ strcpy(check, tab[i]); for(j=0;j<n;j++){ if(strcmp(check, tab[j]) == …
