C Exercises: Replace more than one blanks with a single blank in a input string.
C Basic Declarations and Expressions: Exercise-97 with Solution
Write a C program to replace more than one blanks with a single blank in a input string.
Sample Solution:
C Code:
#include <stdio.h>
int main()
{
long ctr_char, ctr_word, ctr_line;
int c;
int flag;
ctr_char = 0;
flag = ctr_line = ctr_word = 0;
printf("Input a string and get number of characters, words and lines:\n");
while ((c = getchar()) != EOF)
{
++ctr_char;
if (c == ' ' || c == '\t')
{
flag = 0;
}
else if (c == '\n')
{
++ctr_line;
flag = 0;
}
else
{
if (flag == 0){
++ctr_word;
}
flag = 1;
}
}
printf("\nNumber of Characters = %ld",ctr_char);
printf("\nNumber of words = %d",ctr_word);
printf("\nNumber of lines = %d",ctr_line);
}
Sample Output:
Input a string and get number of characters, words and lines: The quick brown fox jumps over the lazy dog ^Z Number of Characters = 44 Number of words = 9 Number of lines = 1

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().
