Program Break When Read a Whitespace C++
C Programming: Divide string by space into words
C Cord: 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 cord by infinite into words :\due north"); printf("---------------------------------------\due north"); printf(" Input a cord : "); fgets(str1, sizeof str1, stdin); j=0; ctr=0; for(i=0;i<=(strlen(str1));i++) { // if space or NULL found, assign Zero into newString[ctr] if(str1[i]==' '||str1[i]=='\0') { newString[ctr][j]='\0'; ctr++; //for adjacent word j=0; //for next word, init alphabetize to 0 } else { newString[ctr][j]=str1[i]; j++; } } printf("\n Strings or words later on split past space are :\northward"); for(i=0;i < ctr;i++) printf(" %s\northward",newString[i]); return 0; } Sample Output:
Split cord by space into words : --------------------------------------- Input a string : this is a examination string Strings or words after split by space are : this is a test string

C Programming - What is the deviation betwixt const int*, const int * const, and int const *?
Read it backwards (as driven by Clockwise/Spiral Rule):
- int* - arrow to int
- int const * - pointer to const int
- int * const - const pointer to int
- int const * const - const pointer to const int
At present the first const tin be on either side of the type so:
- const int * == int const *
- const int * const == int const * const
If y'all want to get really crazy you can practise things similar this:
- int ** - pointer to pointer to int
- int ** const - a const pointer to a pointer to an int
- int * const * - a pointer to a const pointer to an int
- int const ** - a pointer to a arrow to a const int
- int * const * const - a const pointer to a const pointer to an int
- ...
And to brand sure we are clear on the meaning of const:
int a = 5, b = ten, c = 15; const int* foo; // pointer to abiding int. foo = &a; // consignment to where foo points to. /* dummy statement*/ *foo = vi; // the value of a can't get changed through the pointer. foo = &b; // the pointer foo tin be changed. int *const bar = &c; // constant arrow to int // note, you really demand to prepare the arrow // hither because yous tin't modify it later ;) *bar = 16; // the value of c tin can be changed through the pointer. /* dummy argument*/ bar = &a; // not possible because bar is a constant pointer.
foo is a variable arrow to a abiding integer. This lets you alter what you point to but not the value that you point to. Well-nigh often this is seen with C-style strings where you take a pointer to a const char. You may modify which cord you betoken to only you tin't change the content of these strings. This is important when the cord itself is in the data segment of a program and shouldn't exist changed.
bar is a constant or stock-still pointer to a value that tin be changed. This is similar a reference without the extra syntactic carbohydrate. Because of this fact, usually yous would use a reference where you lot would utilise a T* const arrow unless you need to allow Nada pointers.
