Explanation / Answer

#include<stdio.h>

int main(){

float a,b,area;

printf("Enter length and breadth of a rectangle : ");

scanf("%f %f",&a,&b);

area = a*b;

printf("Area of rectangle is %f",area);

return 0;

}

#include<stdio.h>

int main(){

int a,result=0;

printf("Enter number : ");

scanf("%d",&a);

for(int i=0;i<a;i++){

result = result+i+1;

}

printf("Sum from 1 to %d is %d",a,result);

return 0;

}
