A C algorithm will go ...

int t=1;

int i;

for(i=2;i<=5;i++)

The algorithm is as above. I'll explain it to you.

for(i=2;i<=5;i++).

First execute i=2 and then judge i<=5 if correct execute t=t*i; Then do i++ to add 1 to the value of i, and then go back to the above to determine i<=5.The process is looped until i>5 judges that it is incorrect and performs the incorrect operation - exit.

The result is:

t=1*2*3*4*5

Let's see for yourself why this is so.

Defining static variables, it should be possible

s4 is to add one to the variable every time it is executed!

s5 can be executed with a for statement!

#include

void man()

int t=1,i;

for(i=2;i<=5;i++)

t=t*i;

printf("t=%d",t);

Program Execution Process:

s1:int t=1;

s2:int i=2

s3:t=t*i=1*2;

s4:i++;

s5:i=3<=5;

s3:t=t*i=1*2*3;

s4:i++;

s5:i=4<=5;

s3:t=t*i=1*2*3*4;

s4:i++;

s5;i=5<=5;

s3:t=t*i=1*2*3*4*5;

s4:i++;

s5:i=6！<=5;

endfor（i=2[a]，i<=5[b]，i++[c]）t*=i[d];

S2 is given an initial i value, which corresponds to [a].

s3 is a circular execution statement, corresponding to [d].

In S4, i is self-additive, corresponding to [c].

s5 is judged by i<=5 to determine the number of cycles, corresponding to [b].

An algorithm refers to the specific steps and methods required to complete a task. That is, given the initial state or input data, it is possible to derive the required or desired termination state or output data.

Algorithms often contain repetitive steps and some comparisons or logical judgments. Different algorithms may use different time, space, or efficiency to accomplish the same task. The strength of an algorithm can be measured by spatial complexity and temporal complexity.

Once I have learned about data structures, I will have a better understanding of algorithms.
