C Programming: Split string by space into words
C String: Exercise-31 with Solution
Write a program in C to split string by space into words.
Sample Solution:
C Code:
#include <stdio.h>
#include <string.h>
int main()
{
char str1[100];
char newString[10][10];
int i,j,ctr;
printf("\n\n Split string by space into words :\n");
printf("---------------------------------------\n");
printf(" Input a string : ");
fgets(str1, sizeof str1, stdin);
j=0; ctr=0;
for(i=0;i<=(strlen(str1));i++)
{
// if space or NULL found, assign NULL into newString[ctr]
if(str1[i]==' '||str1[i]=='\0')
{
newString[ctr][j]='\0';
ctr++; //for next word
j=0; //for next word, init index to 0
}
else
{
newString[ctr][j]=str1[i];
j++;
}
}
printf("\n Strings or words after split by space are :\n");
for(i=0;i < ctr;i++)
printf(" %s\n",newString[i]);
return 0;
}
Sample Output:
Split string by space into words : --------------------------------------- Input a string : this is a test string Strings or words after split by space are : this is a test string

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().
