Pointer of string with example

 

Pointer of string:

▫️ As we can have the pointer togeneral array, we can also have a pointer to string .

When we storethe string address of the string to the pointer variable, this pointer variable is called as pointer to string.

char      string variable [size],*ptr;

 Ex         ptr = &string1[0];

Example :

#include<stdio.h>

#include<conio.h>

# include<string.h>

main( )

{

    char str[80],*ptr;

     int k,length,count=0, M=0, R=0, U=0, G=0, N=0, A=0, Y=0, N=0, I=0;

    printf("Enter a line of text\n");

    gets(str);

length=strlen(str);

    ptr=str;

for(k=0;k<length;k++)

{

     if( (*ptr=='m') || (*ptr=='M') )

     {      M++;    count++;}

    if( (*ptr=='r') || (*ptr=='R') )

    {      R++;     count++;}

    if( (*ptr=='u') || (*ptr=='U') )

    {      U++;      count++;}

    if( (*ptr=='g') || (*ptr=='G') )

    {      G++;       count++;}

     if( (*ptr=='a') || (*ptr=='A') )

    {      A++;       count++;}

    if( (*ptr=='n') || (*ptr=='N') )

    {      N++;       count++;}

    if( (*ptr=='a') || (*ptr=='A') )

    {       A++;      count++;}

    if( (*ptr=='y') || (*ptr=='Y') )

    {       Y++;      count++;}

    if( (*ptr=='a') || (*ptr=='A') )

    {      A++;      count++;}

     if( (*ptr=='n') || (*ptr=='N') )

     {       N++;     count++;}

     if( (*ptr=='i') || (*ptr=='I') )

     {       I++;     count++;}   

       Ptr++;

}

  printf("Name of character present in screen = %d \n",count);

printf( "M = %d \n",Y);

printf( "R = %d \n",R);

printf( "U = %d \n",U);

printf( "G = %d \n",G);

printf( "A = %d \n", A);

printf( "N = %d \n",N);

printf( "A = %d \n",A);

printf( "Y = %d \n",Y);

printf( "A = %d \n",A);

printf( "N = %d \n",N);

printf( "] = %d \n",]);

}

Output:

Enter the line text
