Computer Science Pdf • we should use single quotes (' ) for a character. • we should use double quotes (") for a string. example: • a char variable takes 1 byte for storage (8 bits). • the value range of a char variable is 128 to 127. strings are arrays of characters in which a special character—the null character—marks the end. example:. In this chapter, we will go through strings in detail. list will be covered in chapter 9 whereas tuple and dictionary will be discussed in chapter 10. string is a sequence which is made up of one or more unicode characters. here the character can be a letter, digit, whitespace or any other symbol.
Computer Science Modules 2 Pdf Integer Computer Science Data Type String declaration & initialization a string in c is nothing but an array of type char two ways to declare a variable that will hold a string of characters: using arrays: char mystr[6] = {'h', 'e', 'l', 'l', 'o', '\0'}; using a string of characters: char mystr [] = "hello"; h e l l o \0 printing strings:. Sscanf(s, " ", ) scans a string (instead of stdin) for expected input sprintf(s, " ", ) outputs to a string (instead of stdout) the specified output. To represent a string of characters, use the data type called string. string is a predefined class in the java library just like the system class. the string type is not a primitive type. the string type is a reference type. strings are immutable! returns true if this string is equal to string s1. Implementing string handling functions •strcpy(dst, src) copies src to dst, character by character up to the ’\0’ void strcpy(char dst[], char src[]) { int i; for (i = 0; src[i] != ’\0’; i ) dst[i] = src[i]; dst[i] = ’\0’; } •strcmp(str1, str2) compares str1 and str2, character by character.

Fundamentals of programming & computer science cs 15 112 strings built in functions & practice dr. hend gedawy. Write a function namediamond that accepts a string parameter and prints its letters in a "diamond" format as shown below. for example, namediamond("shreya") should print:. Strings are declared in c in similar manner as arrays. • only difference is that, strings are of “char” type. example: • to initialize a string variable by assigning all the characters collectively, use double quotes " " str3 [5]; way. str3 = “good”; %s format specifier. → %s is the format string control string for string. Strings, isspace (), , returns true if the string is, non empty and all characters, are white spaces (blank, tab,, newline, carriage return), , >>> str1 = ', , \n, , 183, , \t \r', , >>> str1.isspace (), true, >>> str1 = 'hello, , \n', , >>> str1.isspace (), false, istitle (), , returns true if the string is, non empty and title case, i.e.
