/* Use printf() to print the first 11 characters of source_str. */

printf(?First 11 characters: ?%11.11s?n?, source_str);

by using extract method we can extract a part from the string
strextract(3,7)

this is an uncomplied version....

int i=0,j=0,p;
char *s;
printf("Enter the String");
scanf("%s",&s);
printf(" Enter the start and end of the string: ");
scanf("%d %d",&i,&j);
for(p=i;p<=j;p++)
{
printf("%c",*(s+p);
}
getch()
}

Another solution would be to use strncpy() to copy the part of the string and print it. Below is the code snippet.

int main()
{
char a1[20];
char a2[20];

strcpy(a1,"HelloWorld");
printf("%s ",a1);

strncpy(a2,a1,5);
printf("%s ",a2);

}

The following is much simpler method of printing part of a string.

int main(void)
{
char *ptr = "This is a test string";

/* partial string printing */
printf("String = %s ", &ptr[10]);
return 0;
}

This prints: "test string"

#include"string.h"
void main()
{
int st_index;
int end_index;
char *str;
char* substr(char*,int,int);
printf("enter string");
scanf("%s",str);
printf("enter start index and end index:");
scanf("%d %d",&st_index,&end_index);
printf("the substring is: %s",substr(str,st_index,end_index));
//end of main
}
//function definition
substr(char *temp,int temp1,int temp2)
{
int i,j=0;
char *substr;
for(i=temp1;i<=temp2;i++)
*substr[j++]=*temp[i];
*substr[j+1]='/0';
return substr;
}
