Replace a character by another character in a given string?
C SolutionTo replace a single, specified character with another in a given string, one possibility is ...char *pszString; /* pointer to string */int offset; /* offset of desired character */... initialize pszString and offset*(pszString+offset) = 'A'; /* or whatever new value you want */Obviously, this is a simple example, and it does not consider if offset is greater than the size of the array.If you want to replace every occurence of a character with another, here is another possibility, one that also handles string length ...char *pszString; /* pointer to string */char* pszTemp; /* temporary scanning pointer */char cOldChar; /* character to change */char cNewChar; /* new character */... initialize pszString, cOldChar, and cNewCharfor (pszTemp = pszString; *pszTemp != '\0'; pszTemp++) { /* scan */if (*pszTemp == cOldChar) *pszTemp = cNewChar; /* conditionally replace */}Java Solution// Replace all 'e' characters with 'i' characters in String strstr.replaceAll("e", "i");

There are methods in the String class; toUppercase() and toLowerCase(). i.e. String input = "Hello!"; String upper = input.toUpperCase(); //stores "HELLO!"
