Print last occurrence of a character in a string


Write a C program to Print last occurrence of a character in a string. Here’s simple C program to Print last occurrence of a character in a string in C Programming Language.


C – Strings : 


Strings are actually one-dimensional array of characters terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

String is a sequence of characters. char data type is used to represent one single character in C. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.


Here is source code of the C program to Print last occurrence of a character in a string. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C program to Print last occurrence of a character in a string  */

#include <stdio.h>
#include <string.h>

#define MAX_SIZE 100



/** Function declaration */
int lastIndexOf(const char * text, const char toFind);



int main()
{
    char text[MAX_SIZE];
    char toFind;
    int index;

    printf("\nEnter any string: ");
    gets(text);

    printf("\nEnter any character to find: ");
    toFind = getchar();

    index = lastIndexOf(text, toFind);

    printf("\nLast index of [ %c ] is [ %d ]\n", toFind, index);

    return 0;
}



/**
 * Function to find last index of any character in the given string
 */
int lastIndexOf(const char * text, const char toFind)
{
    int index = -1;
    int i, len;

    len = strlen(text);

    for(i=0; i<len; i++)
    {
        if(text[i] == toFind)
        {
            index = i;
        }
    }

    return index;
}

Output:


/*  C program to Print last occurrence of a character in a string  */

Enter any string: Hello CodezCLub

Enter any character to find: C

Last index of [ C ] is [ 11 ]

Process returned 0

Above is the source code for C program to Print last occurrence of a character in a string which is successfully compiled and run on Windows System.The Output of the program is shown above .
