To Count the Occurence of a Substring in String
#include
#include
#include
char str[100], sub[100];
int count = 0, count1 = 0;
void main()
{
int i, j, l, l1, l2;
clrscr();
printf("\nEnter a string : ");
scanf("%[^\n]s", str);
l1 = strlen(str);
printf("\nEnter a substring : ");
scanf(" %[^\n]s", sub);
l2 = strlen(sub);
for (i = 0; i < l1;)
{
j = 0;
count = 0;
while ((str[i] == sub[j]))
{
count++;
i++;
j++;
}
if (count == l2)
{
count1++;
count = 0;
}
else
i++;
}
printf("%s occurs %d times in %s", sub, count1, str);
getch();
}
Output
Enter a string : prrrogram c prrrogramming
Enter a substring : rr
rr occurs 2 times in prrrogram c prrrogramming

k--;
}
}
for (i = 0;i < k + 1; i++)
{
printf("%s ", str1[i]);
}
}

}
Output
enter string:Welcome to Sanfoundry's C Programming Class, Welcome Again to C class
enter key:Welcome
