Each A is a buffer containing a string, and I want to sort the M strings of A using the strcmp function. The description of the qsort function says that I must pass a pointer to the first object of the array to be sorted. This leads me to write the following: char A; int cmp(...
But that give me compiler warningswarning: assignment from incompatible pointer type, so obviously I'm doing something wrong. Could someone please provide a small but complete example of how to use a function pointer in a C struct correctly? My class taught in C does not even mention these. ...

This article will introduce multiple methods about how to compare strings in C. Use the strcmp Function to Compare Strings The strcmp function is the standard library feature defined in the <string.h> header. C-style strings are just character sequences terminated by the \0 symbol, so the fu...
Whenever you are trying to compare the strings, compare them with respect to each character. For this you can use built in string function called strcmp(input1,input2); and you should use the header file called #include<string.h> Try this code: #include<stdio.h> #include<stdlib.h> #...
Use the strcmp() Function to Compare Strings in PHP The equal operator == use to compare the values of variables and the identical operator === to compare variables with string values and integer values. Then, we will introduce the strcmp() function and compare strings. Use the PHP == ...

For each non-empty slot, we use strcmp to check whether the key at this slot is the one we’re looking for (it’ll be the first one unless there had been a collision). If not, we move along one slot.void* ht_get(ht* table, const char* key) { // AND hash with capacity-1 ...

Yet it would be more elegant IMHO to compute the lengths once and use memcmp() instead of strcmp() which needs more work and is not inlined. You should also define str as a const char * to achieve const correctness and prevent warnings when calling your function with constant strings or...
