C program remove spaces or blanks from a string, For example consider the string
"c programming"
There are two spaces in this string, so our program will print a string
“c programming”. It will remove spaces when they occur more than one time consecutively in string anywhere.

C programming code
#include <stdio.h>
int main()
{
char text[1000], blank[1000];
int c = 0, d = 0;
printf("Enter some text\n");
gets(text);
while (text[c] != '\0') {
if (text[c] == ' ') {
int temp = c + 1;
if (text[temp] != '\0') {
while (text[temp] == ' ' && text[temp] != '\0') {
if (text[temp] == ' ') {
c++;
}
temp++;
}
}
}
blank[d] = text[c];
c++;
d++;
}
blank[d] = '\0';
printf("Text after removing blanks\n%s\n", blank);
return 0;
}
If you want you can copy blank into text string so that original string is modified.

Super concept
it is really amazing!
