C Programming: Sort a string array in ascending order
C String: Exercise-11 with Solution
Write a C program to sort a string array in ascending order.
Sample Solution:
C Code:
#include <stdio.h>
#include <string.h>
void main()
{
char str[100],ch;
int i,j,l;
printf("\n\nSort a string array in ascending order :\n");
printf("--------------------------------------------\n");
printf("Input the string : ");
fgets(str, sizeof str, stdin);
l=strlen(str);
/* sorting process */
for(i=1;i<l;i++)
for(j=0;j<l-i;j++)
if(str[j]>str[j+1])
{
ch=str[j];
str[j] = str[j+1];
str[j+1]=ch;
}
printf("After sorting the string appears like : \n");
printf("%s\n\n",str);
}
Sample Output:
Sort a string array in ascending order : -------------------------------------------- Input the string : w3resource After sorting the string appears like : 3ceeorrsuw

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().
