Nov 28, 2024 · In this article, we will learn how to compare two strings using pointers. To compare two strings using pointers, increment the pointers to traverse through each character of the strings while comparing each character at corresponding position.

Mar 20, 2016 · # include <iostream> using namespace std; int main {char string1 [50], string2 [50], * str1, * str2; int i, equal = 0; printf ("Enter The First String: "); scanf ("%s", string1); printf ("Enter The Second String: "); scanf ("%s", string2); str1 = string1; str2 = string2; while (* str1 == * str2) {if (* str1 == '\0' || * str2 == '\0') break ...

Sep 7, 2022 · Given two strings, compare the strings using pointers. Examples: Output: Both are equal. Input: str1 = hello, str2 = hellu. Output: Both are not equal. The idea is to dereference given pointers, compare values and advance both of them. Complexity analysis: Time Complexity: O (min (M, N)), where M and N represents the length of the given strings.

Sep 8, 2010 · Those should be const char *. You may want to use strcmp: int v; const char *str1 = "hello"; const char *str2 = "world"; v = strcmp(str1, str2); if (v < 0) printf("'%s' is less than '%s'.\n", str1, str2); else if (v == 0) printf("'%s' equals '%s'.\n", str1, str2); else if (v > 0) printf("'%s' is greater than '%s'.\n", str1, str2); return 0; Result:

The compareStrings function is designed to compare two strings. This function uses two pointers ( str1 and str2 ) to iterate through the characters of each string. The while loop inside this function will continue as long as characters from both strings are equal and not the null terminator.

Feb 25, 2010 · In C++ you can use the compare () function. C: char str1[10] = "one"; char str2[10] = "two"; if (strcmp(s, t) != 0) // if they are equal compare return 0. C++. string str1 ("one"); string str2 ("two");

Here is a program that compare two strings in C using loops, strcmp function (inbuilt function) and pointers along with detailed explanations and examples.

Nov 17, 2013 · In below program we are comparing two string with the help of pointers, without using strcmp() function. A user defined function str_cmp() is created which takes two character pointers as argument. If this function returns 1 than the strings are equal and unequal if returns 0.

Given two strings, we have to write a C program to compare them using the pointers. Below are the steps to compare two strings using the pointers: Declare two string variables. Create two pointers for strings, and initialize them with the string …

Jul 7, 2014 · I found ad exercise with a particular function, that help to compare 2 strings using pointers. The solution of the Function is: int i = 0; while( *( a + i ) != '\0' && *( b + i ) != '\0' ){ if( *( a + i ) < *( b + i ) ){ return -1; } else if( *( a + i ) > *( b + i ) ){ return 1; i++; if( *( a + i ) == '\0' && *( b + i ) == '\0' ){ return 0;
