C Program to Find Last Occurrence of a Character in a String

C program to find the last occurrences of a character in a string; Through this tutorial, we will learn how to find the last occurrences of a character in a string using for loop, while loop, recursion, and functions in c programs.

Programs to Find Last Occurrence of a Character in a String in C

Let’s use the following programs to find the last occurrences of a character in a string using for loop, while loop, recursion, and functions in c:

  • C Program to Find Last Occurrence of a Character in a String using For Loop
  • C Program to Find Last Occurrence of a Character in a String using While Loop
  • C Program to Find Last Occurrence of a Character in a String Using Recursion
  • C Program to Find Last Occurrence of a Character in a String using Function

C Program to Find Last Occurrence of a Character in a String using For Loop

#include <stdio.h>
#include <string.h>
 
int main()
{
    char s[1000],c;  
    int i,n,k=0;
 
    printf("Enter  the string : ");
    gets(s);
    printf("Enter character to be searched: ");
    c=getchar();
    
    for(i=strlen(s)-1;i>=0;i--)  
    {
    	if(s[i]==c)
    	{
		  k=1;
    	  break;
		}
 	}
    if(k)
 	    printf("character  %c  is last occurrence at location:%d ",c,i);
    else
        printf("character is not in the string ");
 
 	 
     
    return 0;
}

The Output of the above c program; as follows:

Enter  the string : hello world
Enter character to be searched: o
character  o  is last occurrence at location:7 

C Program to Find Last Occurrence of a Character in a String using While Loop

/* C Program to find Last Occurrence of a Character in a String */
 
#include <stdio.h>
#include <string.h>
 
int main()
{
  	char str[100], ch;
  	int i, index;
  	i = 0;
  	index = -1;
 
  	printf("\n Please Enter any String : ");
  	gets(str);
  	
   printf("Enter character to be searched : ");
   
  	scanf("%c", &ch);
  	
  	while(str[i] != '

int main()
{
char str[100], ch;
int i, index;
i = 0;
index = -1;
printf("\n Please Enter any String : ");
gets(str);
printf("Enter character to be searched : ");
scanf("%c", &ch);
while(str[i] != '\0')
{
if(str[i] == ch)  
{
index = i;	
}
i++;
}
if(index == -1)
{
printf("character is not in the string ");
}
else
{
printf("character  %c  is last occurrence at location:%d ",ch,index);
}	
return 0;
}
') { if(str[i] == ch) { index = i; } i++; } if(index == -1) { printf("character is not in the string "); } else { printf("character %c is last occurrence at location:%d ",ch,index); } return 0; }

The Output of the above c program; as follows:

Please Enter any String : hello world
Enter character to be searched : o
character  o  is last occurrence at location:7 

C Program to Find Last Occurrence of a Character in a String Using Recursion

#include <stdio.h>
 #include <string.h>
 
 
int check(char *s,char c)
{
     int i=strlen(s)-1;
    if(i<0)
    {
        return i;
	}
	else
	{
		 if(s[i]==c)
		 return i;
		 i--;
		 check(s,c);
	}
 
    
 	
 	 
 	
}
int main()
{
    char s[1000],c;  
    int n;
 
    printf("Enter  the string : ");
    gets(s);
    printf("Enter character to be searched: ");
    c=getchar();
    n=check(s,c);
 
     
    if(n>-1)
 	    printf("character  %c  is last occurrence at location:%d ",c,n);
    else
        printf("character is not in the string ");
        return 0;
 }

The Output of the above c program; as follows:

Enter  the string : hello programmer
Enter character to be searched: r
character  r  is last occurrence at location:15 

C Program to Find Last Occurrence of a Character in a String using Function

#include <string.h>
 
int check(char *s,char c)
{
    int i,k=0;
    for(i=strlen(s)-1;i>=0;i--)  
    {
    	if(s[i]==c)
    	{
		  k=1;
    	  break;
		}
 	}
   return i;
 	
	  
 }
int main()
{
 
    char s[1000],c;  
    int n;
 
    printf("Enter  the string : ");
    gets(s);
    printf("Enter character to be searched: ");
    c=getchar();
    n=check(s,c);
 
     
    if(n>-1)
 	    printf("character  %c  is last occurrence at location:%d ",c,n);
    else
        printf("character is not in the string ");
 
 	 
     
    return 0;
 
     
     
}

The Output of the above c program; as follows:

Enter  the string : welcome to c programming
Enter character to be searched: p
character  p  is last occurrence at location:13
