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 ...

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
In C language, %n is a special format specifier. It cause printf() to load the variable pointed by corresponding argument. The loading is done with a value which is equal to the number of characters printed by printf() before the occurrence of %n.Note − It does not print anything. Another printf() function is used to print the statement.Here is an example of %n in C language, Example Live Demo#include int main() { int s; printf("The value of %ns : ", &s); printf("%d", s); getchar(); return 0; }OutputThe value of s : 13Even if we give the ...

Generally, printf() function is used to print the text along with the values. If you want to print % as a string or text, you will have to use ‘%%’. Neither single % will print anything nor it will show any error or warning.Here is an example to print % in printf() in C language, Example Live Demo#include int main() { printf("%"); printf("%%"); getchar(); return 0; }Output%There are some other ways to print % in the text message as in the following example, Example Live Demo#include #include int main() { printf("welcome%"); printf("%%"); printf("%c", '%'); ...

All these functions read the character from input and return an integer. The value of EOF is used for this purpose.getc()It reads a single character from the input and return an integer value. If it fails, it returns EOF.Here is the syntax of getc() in C language, int getc(FILE *stream);Here is an example of getc() in C language, Example Live Demo#include int main () { char val; printf("Enter the character: "); val = getc(stdin); printf("Character entered: "); putc(val, stdout); return(0); }OutputEnter the character: a Character entered: agetchar()The function getchar() reads the character from the standard ...

External variables are also known as global variables. These variables are defined outside the function. These variables are available globally throughout the function execution. The value of global variables can be modified by the functions. “extern” keyword is used to declare and define the external variables.Scope − They are not bound by any function. They are everywhere in the program i.e. global.Default value − Default initialized value of global variables are Zero.Lifetime − Till the end of the execution of the program.Here are some important points about extern keyword in C language, External variables can be declared number of times ...

Register variables tell the compiler to store the variable in CPU register instead of memory. Frequently used variables are kept in registers and they have faster accessibility. We can never get the addresses of these variables. “register” keyword is used to declare the register variables.Scope − They are local to the function.Default value − Default initialized value is the garbage value.Lifetime − Till the end of the execution of the block in which it is defined.Here is an example of register variable in C language, Example Live Demo#include int main() { register char x = 'S'; register int ...

Both strcat() and strncat() are predefined string functions in C++. Details about these are given as follows.strcat()This function is used for concatenation. It appends a copy of the source string at the end of the destination string and returns a pointer to the destination string. The syntax of strcat() is given as follows.char *strcat(char *dest, const char *src)A program that demonstrates strcat() is given as follows.Example Live Demo#include #include using namespace std; int main() { char str1[20] = "Mangoes are "; char str2[20] = "yellow"; strcat(str1, str2); cout
A matrix is a rectangular array of numbers that is arranged in the form of rows and columns.An example of a matrix is as follows.A 3*4 matrix has 3 rows and 4 columns as shown below.8 6 3 5 7 1 9 2 5 1 9 8A program that multiplies two matrices by passing the matrices to functions is as follows.Example Live Demo#include using namespace std; void MatrixMultiplication(int a[2][3],int b[3][3]) { int product[10][10], r1=2, c1=3, r2=3, c2=3, i, j, k; if (c1 != r2) { cout
