Format Specifier %dThe format specifier %d takes integer value as a signed decimal integer value which means values should be decimal whether it is negative or positive.Here is an example of format specifier %d in C language, Example Live Demo#include int main() { int v1 = 7456; int v2 = -17346; printf("The value in decimal form : %d", v1); printf("The value in negative : %d", v2); return 0; }OutputThe value in decimal form : 7456 The value in negative : -17346Format Specifier %iThe format specifier %i takes integer value as an integer value which means ...

Function scanf()The function scanf() is used to read formatted input from stdin in C language. It returns the whole number of characters written in it otherwise, returns a negative value.Here is the syntax of scanf() in C language, int scanf(const char *characters_set)Here is an example of scanf() in C language, Example Live Demo#include int main () { char s[20]; printf("Enter a string : "); scanf("%s", s); printf("Entered string : %s", s); return(0); }OutputEnter a string : Peter! Entered string : Peter!Function fscanf()The function fscanf() is used to read the formatted input from the given stream ... Read More
The function strpbrk() is used to find the first character of first string and matches it to any character of second string. It returns NULL, if no matches are found otherwise, it returns a pointer to the character of first string that matches to the character of second string.Here is the syntax of strpbrk() in C language, char *strpbrk(const char *string1, const char *string2)Here is an example of strpbrk() in C language, Example Live Demo#include #include int main () { const char s1[] = "Helloworld"; const char s2[] = "Blank"; char *result; result = strpbrk(s1, ...

Set gap between Grid columns with CSS. You can try to run the following code to implement the grid-column-gap property.ExampleLive Demo .container { display: grid; background-color: green; grid-template-columns: auto auto; padding: 20px; grid-column-gap: 20px; } .ele { background-color: orange; border: 2px solid gray; padding: 35px; font-size: 30px; text-align: center; } Game Board 1 2 3 4 5 6
The function strcoll() is used to compare two strings using locale - specific collating sequence.It returns −zero, when both strings are same, greater than zero value when first string is greater than otherless than zero value, when first string is less than other.Here is the syntax of strcoll() in C language, int strcoll(const char *first_string, const char *second_string);Here is an example of strcoll() in C language, Example Live Demo#include #include int main () { const char s1[] = "Helloworld"; const char s2[] = "Blank"; char *result; result = strcoll(s1, s2); if(result > 0) ...

For LoopThe for loop is a repetition control structure. It executes the statements a specific number of times. First, it takes the initial value from where it starts the iterations. Second, it takes the condition, which is checked for true, or false. At the end, it increment/ decrement and update the loop variables.Here is the syntax of for loop in C language,for ( init; condition; increment ) { statement(s); }Here is an example of for loop in C language,Example Live Demo#include int main () { int a = 5; for(int i=0;i
Enumeration is a user defined datatype in C language. It is used to assign names to the integral constants, which makes a program easy to read and maintain. The keyword “enum” is used to declare an enumeration.Here is the syntax of enum in C language, enum enum_name{const1, const2, ....... };The enum keyword is also used to define the variables of enum type. There are two ways to define the variables of enum type as follows.enum week{sunday, monday, tuesday, wednesday, thursday, friday, saturday}; enum week day;Here is an example of enum in C language, Example#include enum week{Mon=10, Tue, Wed, Thur, Fri=10, ...

The function iswlower() is a built-in function in C/C++. It checks whether the wide character is in lower case or not. It is declared in “cwctype” header file in C++ language while “ctype.h” in C language. It takes a single character which is known as wide character. It will return zero(0), if the character is not a lower case character. It will return non-zero value, if character is lower case.Here is the syntax of iswlower() in C/C++ language, int iswlower(ch);Here is an example of iswlower() in C++ language, Example Live Demo#include #include using namespace std; int main() { ...

The function iswupper() is a built-in function in C/C++. It converts the wide character into upper case. It is declared in “cwctype” header file in C++ language while “ctype.h” in C language. It takes a single character which is known as wide character. If the character is upper case, it is converted into it, otherwise no modifications happen.Here is the syntax of towupper() in C++ language, wint_t towupper( wint_t ch );Here is an example of towupper() in C++ language, Example#include #include #include using namespace std; int main() { wchar_t s[] = L"hello world!"; wcout Read More
The function iswdigit() is a built-in function in C/C++. It checks whether the wide character is a decimal digit or not. It is declared in “cwctype” header file in C++ language while “ctype.h” in C language. It takes a single character which is known as wide character.The characters from 0 to 9 are classified as decimal digits. If the wide character is not a digit, it will return zero(0). If character is digit, it will return non-zero value.Here is the syntax of iswdigit() in C++ language, int iswdigit(ch)Here is an example of iswdigit() in C++ language, Example Live Demo#include #include ...
