Printf(), scanf(), getchar(), and putchar() are examples of I/O routines. These features are necessary to develop interactive programs that respond to user interaction. Pre-Defined Functions in C Language The C language has been equipped with a large number of built-in functions, which ...
In the C Programming Language, the scanf function reads a formatted string from the stdin stream.SyntaxThe syntax for the scanf function in the C Language is:int scanf(const char *format, ...);Parameters or Argumentsformat Describes the input as well as provides a placeholder to insert the ...
In this article, we are going to learn about thefscanf() function of stdio.h header file in C programming languageand use it to scan rewind variables. Submitted byAbhishek Sharma, on April 13, 2018 This function is just likescanf()function, but instead of standard input, this read data ...
scanf("%d",&n); int fact = factorial(n); printf("\nThe factorial of %d is: %d\n", n, fact); return 0; } Output: Enter the number: 5 The factorial of 5 is: 120 In the C program, we have created the recursive function factorial(), in which there is one base to terminate ...
In the various programming languages like C, we always encounter programs that contribute to taking the input from the user in the form of any value typed from the keyboard input, which involves the use of the scanf() method. But several other programs exist where we want to read the data...
scanf("%s",string_2); intcompare_result; compare_result=strcasecmp(string_1,string_2); if(compare_result==0) printf("equal strings"); else printf(" not equal"); return0; } The two user-defined strings were “Chairs” and “TABLE”, respectively. The result of the comparison came out...
Example: Sum of Natural Numbers Using Recursion #include <stdio.h> int sum(int n); int main() { int number, result; printf("Enter a positive integer: "); scanf("%d", &number); result = sum(number); printf("sum = %d", result); return 0; } int sum(int n) { if (n != 0...
scanf("%d", &divisor); // Call the divide function int result = divide(dividend, divisor); // Check the result of the divide function if (result == -1) { // Handle error condition printf("Division failed. Please check your input.\n"); ...
printf("Division of two numbers\n"); scanf("%d%d", &x, &y); assert(y != 0); printf("%d/%d = %.2f\n", x, y, x/(float)y); return 0; } Output: Assert() Ignoring C Programming By using GCC, C, and C++ compilers the code will be generated, and assertions are enabled by...
