Program to show the effect of increment / decrement operator  Source Code: #include<stdio.h> #include<conio.h> int main( ) { int x; clrscr( ); printf("\nEnter the value of x::"); scanf("%d",&x); printf("\n x++ After the post increment is::%d",x++); printf("\n The changed value of x is::%d",x); printf("\n\nEnter the value of x::"); scanf("%d",&x); printf("\n --x After the pre decrement is::%d",--x); printf("\n The changed value of x is::%d",x); return 0; } Output: Follow our site for more program like this.. 

Program to show similarity between int and char Source Code: #include<stdio.h> #include<conio.h> int main() { int i; char c; printf("\nenter an integer"); scanf("%d", &i); // Input-65 printf("\nenter a character"); fflush(stdin); // Clears input buffer there may be space or new line char in input buffer scanf("%c", &c);// Input-A printf("\n%d", c);//Answer=65 //prints ASCII code of character stored in variable c printf("\n%c", i); Answer=A //prints character corresponding to the value store in i i=i+1; c=c+1; printf("\n%d", i);// Answer=66 printf("\n%c", c);// Answer=B return 0; } Output: Follow our site for more program like this.. 

WAP to input 3 sides of triangle and calculate area. Source Code: #include<conio.h> #include<stdio.h> #include<math.h> int main() { float a,b,c,s,A; printf("\n enter the value of the sides of the triangle:"); scanf("%f%f%f",&a,&b,&c); s=(a+b+c)/2; A=sqrt(s*(s-a)*(s-b)*(s-c)); printf("\n the area of the triangle is:%f",A); return 0; }
