Question

wap to print (1,-3,5,-7 to n) in C-language
​

Answer 1

Solution:

The given cøde is written in C.

#include <stdio.h>

int main(){

int n,i,a=1,c=1;

printf("Enter n - ");

scanf("%d",&n);

for(i=0;i<n;i++,a+=2,c*=-1)

printf("%d ",c*a);

return 0;

}

Logic:

• Ask the user to enter the limit.
• Initialise a=1, c=1
• Iterate a loop n times.
• Display value of c × a.
• Increment value of a by 2.
• Negate the value of c as terms are either positive or negative.
