The tolower() function is used to translate uppercase characters to lowercase characters. The function is defined in the ctype.h header file. Syntax: int tolower(int argument); tolower() Parameters: Return value from tolower() Upon successful completion, tolower() returns the lowercase letter...
In this case, we created a functiontoLowerthat takeschar*, where a null-terminated string is stored and asize_ttype integer denoting the string’s length. The function allocates the memory on the heap using thecallocfunction; thus the caller is responsible for deallocating the memory before ...
char u = 'A'; char l = tolower(u); printf("%c in lowercase is %c", u, l); Try it Yourself » Definition and UsageThe tolower() function returns the ASCII value of a lowercase version of the character. If the character is not an uppercase character then its value is returned...
char upper2lower(char ch){ return ch|=0x20;} void main(){ char ptr[11]="Fun Course";char outstr[11];int i;for(i=0;ptr[i];i++){ outstr[i]=upper2lower(ptr[i]);} outstr[i]='\0';printf("%s\n",outstr);} ...
C program to reverse a string without using library function C program to split string by space into words C program to toggle each character of a string C program to count upper case and lower case characters in a string C program to count digits, spaces, special characters, alphabets in ...
printf("Lower case string is: %s\n",s); return0; } The step is to integrate the required libraries. #include <stdio.h> and #include <cstype.h>. Then we define the main() function. Within the body of this function, we initialize variable ‘s’ for the string. Here we specify the...
Write a program in C program to convert a string to uppercase or lowercase using a callback function to modify each character. Sample Solution: C Code: #include<stdio.h>#include<ctype.h>voidmodify_string(char*str,int(*modifier)(int)){while(*str!='\0'){*str=modifier(*str);str++;}...

MFC's conversion function is cool. It lets you pass a CString anywhere you could pass a pointer to a C string. It lets you write CString s = "whatever"; MyFunc(s); // MyFunc wants LPCTSTR whereas with STL, you have to explicitly invoke string::c_str. ...
