#include <stdio.h>

/* Returns the number of occurrences of string t in s

*

* Example:

* substring_n("hello", "el") => 1

* substring_n("", "ab") => 0

* substring_n("utilities", "ti") => 2

{

return -1;

Answer 1

ANS:

#include<stdio.h>
using namespace std;

int substring(char *s,char*t)
{
int j;
int count=0;
int subcount=0;
int index=0;
while(t[index]!='\0')
{
subcount++;
index++;
}
  
for(int i=0;s[i]!='\0';i++)
{
for( j=0;t[j]!='\0';j++)
{
if(s[i+j]!=t[j])
{
break;
}
}
  
if(index==j)
{
count++;
j=0;
}
}
return count;
}

int main()
{
char *str1=new char[50];
char *str2=new char[20];
printf(" Enter the first string:");
scanf("%c",str1);
  
printf(" Enter the first string:\n");
scanf("%c",str2);
  
printf("%d Count:",substring(str1,str2));
  
  
  
}
