A function is a piece of code that can be used repeatedly in a C program. A function is mainly of two types: Built in Functions; which are already defined in C Library. User Defined Functions; which are created and defined by users. Syntax: Return_type functionName(parameters) { code to be executed; } … Read more
Type casting in C simply means to convert one data type into other. C facilitates with a special operator named (type) which serves the purpose of type casting, where type represents the required data type. Syntax: (type) value; Example: #include<stdio.h> void main() { char value= (char)66; printf("Value : %c\n", value ); }#include<stdio.h> void main() { … Read more
C goto statement is used to jump to a specified label in the code every time, without any condition. Syntax: loop/conditions statements { statements; goto; } Example: #include <stdio.h> void main() { int i,n; printf ("Enter a number: "); scanf ("%d",&n); less: printf ("less than 5"); if (i < 5) goto less; … Read more
C Continue statement is used to skip the execution of current iteration in between the loop. Continue statement controls the containing loop only, i.e, external loops will not get affected because of Continue statement in inner loop. Syntax: loop/conditions statements { statements; continue; } Example: #include <stdio.h> void main() { int i,j; for … Read more
C break statement is used to break the execution of current loop in between the loop or to prevent the code to check the next switch case. Break statement breaks the continuity of the containing loop only, i.e, external loops will not get affected because of Break statement in inner loop. Syntax: loop/conditions statements { … Read more
