String handling functions:
1. strlen(): This function tells the number of character in a string. This will be as follows: l=strlen(string);
where l is integer.
2. strcat(): This function is use to combine two strings. This will be as follows:
strcat(string1,string2);
in this function the string2 is appended to string1 and it removes the ‘ ’ from string1.
3. strcpy(): This function is use to copy the contents of string to another. This will be as follows:
strcpy(string1,string2);
this will copy the content of string2 to string1. And we can give string constant instead of character array.
e.g: strcpy(subject,”programming in c”);
4. strcmp(): This function is use to compare two strings. This will be as follows:
strcmp(string1,string2);
this will compare the both strings. And if they are equal this will return 0. Otherwise it will returns the numeric difference in both according to ASCII values.
