Chap 9[D]d Working with strings is fun

Write a program that extracts part of the given string from the specified position. For example, if the sting is "Working with strings is fun", then if from position 4, 4 characters are to be extracted then the program should return string as "king". Moreover, if the position from where the string is to be extracted is given and the number of characters to be extracted is 0 then the program should extract entire string from the specified position.


void main()
{
char stri[]="Working with string is fun";
char stri2[10];
int a,flag=0,i=0,b;

printf("\nEnter a position for sentence: Working with string is fun");
scanf("%d",&a);

while(flag==0)
{
if(i==(a-1))
{
if(stri[i]==32)
{
i++;
for(b=0;;b++,i++)
{

if(stri[i]==32||stri[i]=='\0')
{
stri2[b]='\0';
break;
}

stri2[b]=stri[i];
}
}

else

for(b=0;;b++,i++)
{

if(stri[i]==32||stri[i]=='\0')
{
stri2[b]='\0';
break;
}

stri2[b]=stri[i];
}
flag=1;
}

i++;
}
printf("\n%s",stri2);
}
