C Programming: Find the largest and smallest word in a string
C String: Exercise-20 with Solution
Write a program in C to find the largest and smallest word in a string.
Sample Solution:
C Code:
#include <stdio.h>
#include <string.h>
#include <ctype.h>
void main()
{
char str[100], word[20], mx[20], mn[20], c;
int i = 0, j = 0, flg = 0;
printf("\n\nFind the largest and smallest word in a string :\n");
printf("-----------------------------------------------------\n");
printf("Input the string : ");
i = 0;
do
{
fflush(stdin);
c = getchar();
str[i++] = c;
} while (c != '\n');
str[i - 1] = '\0';
for (i = 0; i < strlen(str); i++)
{
while (i < strlen(str) && !isspace(str[i]) && isalnum(str[i]))
{
word[j++] = str[i++];
}
if (j != 0)
{
word[j] = '\0';
if (!flg)
{
flg = !flg;
strcpy(mx, word);
strcpy(mn, word);
}
if (strlen(word) > strlen(mx))
{
strcpy(mx, word);
}
if (strlen(word) < strlen(mn))
{
strcpy(mn, word);
}
j = 0;
}
}
printf("The largest word is '%s' \nand the smallest word is '%s' \nin the string : '%s'.\n", mx, mn, str);
}
Sample Output:
Find the largest and smallest word in a string : ----------------------------------------------------- Input the string : It is a string with smallest and largest word. The largest word is 'smallest' and the smallest word is 'a' in the string : 'It is a string with smallest and largest word'.

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
